Volume is measured using bidirectional ultrasonic technique based on the transit time method, proven a long‐term stable and accurate measuring principle. Through two ultrasonic transducers the sound signal is sent both with and against the flow. The ultrasonic signal travelling with the flow reaches the opposite transducer first. The time difference between the two signals can be converted into flow velocity and thereby also volume. Accurately matched Pt500 or Pt100 sensors measure inlet and outlet temperatures according to EN 60 751. MULTICAL® 403 normally comes with a Pt500 sensor pair, e.g. short direct sensors according to EN 1434‐2, or ø5.8 mm pocket sensors, which fit Kamstrup sensor pockets in stainless steel. Accumulated heat energy and/or cooling energy can be displayed in kWh, MWh or GJ, all in the form of seven or eight significant digits plus measuring unit. The display has been specially designed with a view to obtaining long lifetime and sharp contrast in a wide temperature range. Other reading options are: accumulated water consumption, operating hour counter, error hour counter, current temperature measurements, current flow and power readings. Furthermore, MULTICAL® 403 can be configured to ...

The average is volume based. Only the date of min/max is displayed in the format 20xx.xx.xx. Serial reading includes the time (hh.mm) of the average value calculation too. Inputs A and B are currently updated in the display of MULTICAL® 403, i.e. the display of the connected water or electricity meter will be in accordance with the display of MULTICAL® 403 without delay. The unit of this reading is fixed at kW. 3.2.5 Tariffs >EE< MULTICAL® 403 has 3 extra registers TA2, TA3 and TA4, which can accumulate heat energy or cooling energy (EE=20 accumulates volume) parallel with the main register based on pre‐programmed tariff conditions (to be stated in the order). Irrespective of the selected tariff type the tariff registers are named TA2, TA3 and TA4 in the display. As the main register is considered the legal billing register, it is accumulated no matter the selected tariff function. Tariff conditions TL2, TL3 and TL4 are monitored at all integrations. If the tariff conditions are fulfilled, consumed heat energy is accumulated in TA2, TA3 or TA parallel with the main register. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 26 ...

MULTICAL® 403 Example of power tariff (EE=11) Power (P) Integrations Three tariff conditions, TL2, TL3 and TL4, which are always used in the same tariff type, are connected to each tariff function. Therefore, it is not possible to “mix” 2 tariff types, except from the PQ‐tariff (EE=21). TA2 shows energy consumed… …above the power limit TL2 IMPORTANT: Out of consideration for backwards compatibility tariff register TA4 can be deactivated. Thus, the meter uses TA2 and TA3 only, and the tariff function works as in the previous model, MULTICAL® 402. TA4 is deactivated by setting the tariff limit TL4 at 0.

The tariff function can, however, at a later stage be activated through reconfiguration via METERTOOL HCW. See paragraph 14. EE=11 Power controlled tariff If the current power (P) exceeds TL2 but is lower than or equal to TL3, energy is counted in TA2 parallel to the main register. If the current power exceeds TL3 but is lower than or equal to TL4, energy is counted in TA3 parallel to the main register.

The flow controlled tariff is e.g. used as a basis for the individual heat consumer’s connection fee. Furthermore, this tariff type can provide valuable statistical data if the heating station considers new construction activities. When either power or flow tariff is used you obtain an overview of the total consumption compared to the part of the consumption used above tariff limits. EE=13 t1‐t2 tariff (Θ) If the current t1‐t2 (Θ) is lower than TL2 but exceeds or is equal to TL3, heat energy is counted in TA2 parallel to the main register. If the current cooling becomes lower than TL3 but is higher than or equal to TL4, energy is counted in TA3 parallel to the main register. If the current t1‐t2 (Θ) is lower than TL4, energy is counted in TA4 parallel to the main register. Θ TL2 Accumulation in main register only TL3 Θ TL2 Accumulation in TA2 and main register TL4 TL3 TL2 Accumulation in TA3 and main register TL4 Θ TL3 Θ TL4 Accumulation in TA4 and main register Setting up tariff limits, TL3 must be lower than TL2 and TL4 must be lower than TL3.

The inlet temperature tariff can be used as a basis for billing consumers who are guaranteed a certain inlet temperature. If the “guaranteed” minimum temperature is entered in TL4, the payable consumption is accumulated in TA4. EE=15 Outlet temperature tariff If the current outlet temperature (t2) exceeds TL2 but is lower than or equal to TL3, energy is counted in TA2 parallel to the main register. If the current outlet temperature exceeds TL3 but is lower than or equal to TL4, energy is counted in TA3 parallel to the main register.

66 Modbus RTU + 2 Pulse inputs (In‐A, In‐B) 67 MULTICAL 403 registers the accumulated consumption of the meters connected to inputs A and B and saves the counter values every month and every year on target date. The number of these yearly and monthly loggings depends on the selected logger profile (RR‐code). Read more about data logger profiles in paragraph 3.2.11. In order to make identification easier during data reading, the meter numbers of the two meters connected to inputs A and B can be saved too. The meter numbers can be programmed into the meter in SETUP loop or via METERTOOL HCW. Two alarm types are connected to the pulse inputs, cold water leakage and external alarm respectively. Unless otherwise informed by the customer, the meter is by default prepared for external alarm on both inputs from the factory, but only with active leakage alarm on input A (like in MC402).

When the system is stable again, the meter gradually returns to the 64 s. interval. MULTICAL® 403 reacts quickly to changes in the system by reducing the time interval to 4 seconds; however, it gradually returns to the time interval of 64 s. as the system becomes stable. Thus, in adaptive mode MULTICAL® 403 measures at high resolution during periods with changes in the system requiring accurate measurements, and saves battery power during stable periods. Adaptive mode is recommended for all systems including those with tap water exchanger. Normal mode (32 s) In normal mode the integration interval is set at 32 seconds, which means that the meter calculates accumulated volume and energy every 32 seconds. Normal mode is recommended for systems with hot water tank and similar systems. Fast mode (4 s) In fast mode the integration interval is set at 4 seconds, which means that the meter calculates accumulated volume and energy every 4 seconds. Fast mode is recommended for all systems including those with tap water exchanger. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 35 ...

If controlled output is required, the PP‐code is to be configured at 99. During the configuration connected external equipment can switch the meter’s outputs C and D OFF (open optotransistor output) and ON (closed optotransistor output) respectively via KMP data commands. Output status can be read via the KMP‐registers. After a power‐on reset the outputs will have the same status as before the power interruption as every change of status is saved in the meter’s EEPROM. 3.2.10 Data logger profile >RR< MULTICAL 403 has a permanent memory (EEPROM), in which the results from various data loggers are saved. The data logger is programmable. The required data logger profile is selected via the RR‐code of the configuration number. Unless otherwise stated by the customer, the RR‐code is set at 10, which is the default data logger profile (equal to the data logger in MC602). If data logging of other registers, different intervals and logging depths are required, data logging profiles can be composed to match individual requirements.

403 must be ordered with encrypted data transmission between module and reading system. Data is encrypted with 128 bit AES counter mode encryption. Data transmission can be encrypted with either a common or an individual encryption key. If you choose individual encryption key (T‐code 3) the reading system must know the encryption key of each meter in order to read the meter. The encryption key is sent to the customer and then ”matched” with the serial number of the individual meter in the reading system. If you choose common encryption key (T‐code 2) the key can be used for reading a customer specific number of meters. The key is created by Kamstrup A/S. A customer can have several encryption keys, e.g. one for each meter type. Note: The common encryption key is only offered to customers on request. The encryption level is configured as part of the meter’s configuration number via the T‐code.

MULTICAL® 403 4 Installation 4.1 Installation requirements Prior to installation of MULTICAL® 403 the heating system should be flushed while a fitting piece replaces the meter. Remove the adhesive wafers from the meter’s inlet and outlet and mount the flow sensor with couplings/flanges. New fibre gaskets in original quality must be used. If other couplings than the original ones from Kamstrup A/S are used you must make sure that the threaded lengths of the couplings do not prevent proper tightening of the sealing surface. The meter is configured for mounting of flow sensor in inlet or outlet before commissioning, see paragraph 6.3 about SETUP loop. The flow direction is indicated by an arrow on the flow sensor. In order to avoid cavitation the back pressure (the pressure at the flow sensor outlet) at the flow sensor must be minimum 1 bar at q and minimum 2 bar at q , however 1.5 and 2.5 bar respectively for q 15 flow sensor. This applies p to temperatures up to approx. 80 °C. See paragraph 4.4 re operating pressure. When the installation has been completed, water flow can be turned on. The valve on the flow sensor's inlet side must be opened first. The flow sensor must not be exposed to lower pressure than ambient pressure (vacuum). Permissible operating conditions Ambient temperature: 5…55C (indoors). Max. 30 C for optimum battery lifetime. Medium temperature of heat meter: 2…130 C with calculator mounted on a wall 15…90 C with calculator mounted on flow sensor Medium temperature of cooling meter: 2…130 C with calculator mounted on a wall Medium temperature of heat/cooling meter: 2…130 C with calculator mounted on a wall System pressure: 1.0…16 bar for threaded meters (See paragraph 4.4) ...

1.2…20 2 15 1.5 30 2.5 Table 2: Recommended back pressure at various flow sensor sizes The values in the table apply to temperatures up to approx. 80 °C The purpose of recommended back pressure is to avoid measuring errors as a result of cavitation or air in the water. Cavitation does not necessarily happen in the sensor itself, but can also occur as air bubbles created by pump cavitation and regulating valves mounted before the sensor. It can take considerable time until such bubbles have been dissolved in the water. Furthermore, water can include dissolved air. The amount of air which can be dissolved in water depends on pressure and temperature. This means that air bubbles can be formed due to a pressure drop in the installation, e.g. caused by a velocity rise in a contraction or above the sensor. The risk of influence from the above is reduced by maintaining a fair pressure in the installation. In relation to table 2, the steam pressure at current temperature must be considered too. The values in the table apply to temperatures up to approx. 80 °C, the graph in Diagram 2 applies to higher temperatures. Furthermore, it must be taken into consideration that the mentioned pressure is the back pressure at the flow sensor outlet and that the pressure is lower in a contraction than before one, e.g. in case of cones. This means that the pressure, if measured elsewhere in the installation, may differ from the pressure at the flow sensor. The explanation of pressure drop due to velocity increase is found by combining the continuity equation and Bernoulli’s equation. The total energy from the flow will be the same at any cross section. It can be reduced to: P + ½v = constant. where: P = pressure, density, v = velocity. Dimensioning a flow sensor you must take the above into account, especially if the sensor is used in the area between and q described in EN 1434 , and in case of heavy contractions of the pipe.

4 Tariff registers/tariff limits 9 The meter’s radio communication is switched on or off 5 Measuring unit The meter uses four different display loops. The four loops are intended for four different usage situations. USER loop The meter’s configurable display loop, which is intended for the user. The readings in this loop can be adjusted to the utility company’s requirements via the DDD‐code. See paragraph 3.2.4 for an overview of possible readings in the meter’s USER loop. The same paragraph includes examples of DDD‐codes. TECH loop This loop is intended for technicians and is not configurable. The loop displays all the meter’s readings. The loop includes readings like serial number, date, time, config number, software revision and segment test. See paragraph 6.2 for a complete overview of the readings. SETUP loop SETUP loop is also intended for the technician. In this loop the technician can configure the meter via the front keys. In general (unless otherwise requested by the customer) the loop is open in transport state. When the first integration has been carried out by the meter, the access to SETUP loop is blocked. From now on it is no longer possible to access SETUP loop unless you break the installation seal. See paragraph 6.3 for further details about the various parameters which can be configured in SETUP loop and see paragraph 7.8 for details on the meter’s transport state. TEST loop Used by authorized laboratories for reverification of the meter. This loop is not available unless the meter’s test seal (verification seal) is broken. 54 Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 ...

In order to facilitate the diagnostics work, lines are shown in the display readings (current values) which are influenced by the error, and at the same time counting stops in the registers, which are influenced by the error. In case of interrupted or short‐circuited temperature sensor the corresponding display reading will include lines. No lines are shown for flow measurement in case of flow sensor error “wrong flow direction” as this error does not prevent the meter from measuring. If the flow sensor is prevented from measuring, e.g. due to air in the flow sensor, the reading includes lines. The meter registers these errors and sets an info code, which can easily be read from the meter’s display. Read more about the meter's info codes in paragraph 7.7.

How to enter SETUP loop? 1. In general (unless otherwise requested by the customer) SETUP loop is available when the meter is in transport state. The meter leaves transport state at the first integration or if SETUP loop is ended by the menu point ”EndSetup”. A total reset of the meter is the only way to return to transport state. 2. When the meter is in operation, i.e. the meter has left transport state, SETUP loop can be accessed by breaking the meter’s installation seal and separating meter top from meter base. How to end SETUP loop? You can exit SETUP loop in three ways. All three ways can be used both in transport state and after commissioning of the meter. 1. Keep the primary key activated and navigate to the meter’s other loops. 2. After 4 minutes the meter will time out and revert to the first reading in USER loop. 3. Navigate to the menu point ”EndSetup” in SETUP loop and keep the secondary key activated for 5 seconds. Note: This locks the access to SETUP loop, and thereby the meter is locked against further configuration. Subsequent reconfiguration of the meter requires that you break the installation seal. IMPORTANT: EndSetup is an important function when the meter is in transport state, but when the meter is in operation, EndSetup is just one of three ways to exit SETUP loop. As it appears from the table overleaf the purpose of menu point ”EndSetup” is to enable the technician to lock the access to SETUP loop in transport state and thus lock the meter against further configuration. This function is e.g. relevant to a technician who knows that a meter is to be mounted in the installation for some time before the first integration will be carried out and wants to lock the access to SETUP loop immediately after the installation to make sure that no further configuration is possible.

Access to SETUP loop Access to SETUP loop locked Time out Access to SETUP loop Access to SETUP loop locked EndSetup Access to SETUP loop Access to SETUP loop locked locked 6.3.1 Change of parameters in SETUP loop The user can navigate to SETUP loop from USER loop by keeping the primary key activated for 9 seconds. SETUP loop does not include secondary readings, and, therefore, the index number always consists of 4 digits. In SETUP loop the secondary key is used to access individual readings with the purpose of changing the parameter in question. Pressing the secondary key, the first digit of the parameter in question (the digit farthest the left) starts flashing. The flashing digit can now be changed through brief activations of the secondary key. A brief activation of the primary key moves focus to the next digit. Pressing the primary key when focus is on the last digit (the digit farthest to the right) the meter saves the change and “OK” appears in the display. Note: A change of the B‐CCC code is not saved until you leave SETUP loop. Depending on the meter’s configuration one or more menu points in SETUP loop will be displayed as “Off”. This means that the function is not available in the meter, i.e. the function has been disabled during factory programming. If you try to access these readings via the secondary key, the frames around ”Off” will become illuminated to indicate that the function is not available in the meter.

‐ If the meter’s radio communication is switched off via SETUP loop, the meter switches on radio communication again at the next integration (calculation of energy and volume). ‐ The symbols for radio on/off indicate whether the meter allows radio communication, not whether a radio module has activated its radio communication. Please be aware of this when troubleshooting the meter’s wireless communication. The above definition of the radio on/off symbols simplify the use of radio on/off in SETUP loop too as it is possible to toggle radio on/off whether a module is mounted in the meter or not. This fact offers the customer flexibility as the customer can configure the meter prior to mounting a module and thus, make sure that radio is either switched on or switched off by default when the module is subsequently mounted. If there is either not installed a module in the meter or the mounted module is not a radio module, both symbols will be turned off in the meter’s other loops, regardless of the setting of the radio (on/off) in the SETUP loop.

The tariff limits are only active if a tariff type has been selected during configuration of the meter, i.e. the EE‐code differs from ”00”. The EE‐code is shown in TECH loop, see paragraph 6.2. If a tariff type has been selected, the menu points reflect this by displaying the correct tariff limit units. If no tariff type has been selected the menu points will be without units. Read more about tariff types in paragraph 3.2.5. Note: It is not possible to have different types of tariff limits. The display readings shown are just examples. 21. Presetting t5 The value of temperature value t5 can be adjusted in SETUP loop. This value is used in connection with the calculation of outlet energy registers, i.e. registers A1 (A‐, heat at a discount) and A2 (A+, heat with an addition). Read more about this calculation and function in paragraph 7.1.2. 22. EndSetup The menu point ”EndSetup” enables the technician to lock the access to SETUP loop in transport state and thus lock the meter against further configuration. In order to do so, the user must keep the secondary key activated for five seconds. During the five seconds the frames around the reading EndSetup will currently become illuminated in the meter’s display. This action can be undone by releasing the secondary key before the whole frame has become illuminated, i.e. before the five seconds have passed.

No counting 7.2 Measurement of the coefficient of performance (CP) of a heat pump In houses with heat pumps with an output it is expedient to measure both the released thermal energy and the gained electrical energy, based on which the coefficient of performance (COP or CP) can be calculated. COP is the abbreviation of ”Coefficient Of Performance”. The calculation is based on simple proportional numbers between calculated thermal energy (E1) and electrical energy, which is measured via pulse input B (Input B): 1 Electrical energy (Input B) is always registered in kWh, whereas thermal energy (E1) is either registered in kWh, MWh or in GJ depending on the selected B‐code. No matter which unit you choose the meter calculates CP correctly. The CP value is displayed with one decimal and is a value in the interval 0.0…19.9. The CP value can be displayed as a current value, a monthly value or a yearly value. In addition the averaging period of the current CP‐value as well as the current power measured at input B can be displayed. Current CP is averaged over a number of days and nights determined by the meter’s configuration. The averaging period can be selected in the interval 5…30 days and nights. The averaging period is set at 7 days and nights, unless otherwise stated by the customer. Note: If data of E1 or input B are missing for a logging period, current CP is displayed as 0.0 until the data basis is sufficient. The monthly values are calculated as the average of a full month. The month is determined by the selected target date. The yearly values are calculated as the average of a full year. The year is determined by the selected target date.

7.2.1 Measurement of the coefficient of performance (CP) of a gas boiler If the pulse output of a gas meter is connected to a heat meter, the coefficient of performance of the gas boiler can be measured, in terms of e.g. kWh/Nm gas. A volume resolution which corresponds to the pulse weighting on the gas meter pulse output must then be selected for input B. 7.3 Offset adjustment of temperature sensor measurement MULTICAL® 403 is available with possible offset adjustment of the temperature sensor measurement, thus increasing the accuracy of the absolute temperature measurement. This is especially relevant in the installation scenario that the meter is to be used for tariff billing based on absolute temperatures. In that case it is an EN1434 requirement that the accuracy of the meter’s absolute temperature reading must be within ± 1,0 K. Offset adjustment is extremely relevant in district cooling installations too. In district cooling installations the customer often requires a maximum inlet temperature. Absolute temperature measurement measuring with undesirable inaccuracy can cause the supplier to supply water with a lower inlet temperature than promised, resulting in unnecessary extra costs for the supplier. Depending on the meter’s configuration, offset adjustment can be programmed into the meter from the factory. Offset can also be adjusted after delivery via the meter’s SETUP loop (see paragraph 6.3) or via METERTOOL HCW (see paragraph 14). Note: Depending on the meter’s configuration offset adjustment can be disabled and the menu point in SETUP loop will in that case display “Off”. If the temperature sensor pair of a meter with offset adjustment is replaced, we recommend that offset is corrected to match the newly connected sensor pair. Alternatively, offset should be adjusted to 0.00 K, which means that the function is switched off and does not contribute to an undesirable increase of the error of the absolute temperature measurements. Temperature sensor offset (t ) can be adjusted in the interval ‐0.99…0.99 K according to the meter’s approval. Please be aware of that the required offset adjustment must be entered, not the error of the temperature sensor pair. If the selected temperature sensor pair contributes with an error of ‐0.20 K, the meter’s offset must be set Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 80 ...
XX If MULTICAL® 403 has been supplied as a heat/cooling meter (meter type 3 and 6), heat energy (E1) is measured at a positive temperature difference (t1>t2) whereas cooling energy (E3) is measured at a negative temperature difference (t1<t2). Temperature sensor t1 (marked in red) is mounted in the inlet, whereas t2 (marked in blue) is mounted in the outlet. θ functions as a limit value for cooling energy measurement. This means that cooling energy is only measured when the inlet temperature t1 is lower than θ . In heat/cooling meters the limit value θ should be set at the highest temperature which has appeared in the inlet in connection with cooling, e.g. 25 °C. If the meter is to be used for billing, the function θ is disabled. Thereby, the differential temperature alone decides whether cooling or heat energy is invoiced. Configuration of the θ function is only possible in meter type 6. Configuration is possible in the interval 0.01..180.00 °C. In order to disable θ it must be configured at 250.00 °C. In other meters than meter type 6, θ is permanently hc ”Off” in the configuration. θ is configured via SETUP loop or by means of the PC‐program METERTOOL HCW, see hc paragraph 6.3 and 14 for more details. Note: There is no hysteresis in connection with shift between heat and cooling energy measurement (Δθ = 0.00 K). Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 81 ...

All minimum and maximum values are calculated as the average of a number of current flow or power measurements. After each averaging period the latest value is compared to previous values, and the new value is saved if it exceeds the previous maximum value or is lower than the previous minimum value. The averaging period used for all calculations can be selected in the interval 1...1440 min. in leaps of one minute. (1,440 min. = 24 hours). The averaging period and the target dates are stated in the order. Read more about order data in paragraph 3.3. If not otherwise stated in the order, the default averaging period of 60 min. is used. This value can later be changed via SETUP loop or via METERTOOL HCW. Please note the following: In the display the date is shown in the format 20YY.MM.DD, but by serial reading the time can be stated too, and the format then becomes YY.MM.DD, hh.mm.ss. The averaging period starts the moment the meter is powered, i.e. when the battery is mounted in the meter or when mains supply is switched on. Therefore, the averaging period is not necessarily synchronous with the change of day. Due to this fact the min./max. calculation is immune to the clock setting as the interval is kept intact at e.g. 60 or 1440 min. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 83 ...

It is possible to see the information code in bit format using LogView HCW. In case of several simultaneous information codes, the sum of all the codes will be shown. The information code is sent in bit format via data communication as well.. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 85 ...
Info‐event counter If you activate the meter’s secondary key when the info code is displayed you are informed how many times the info code has been changed. The value is increased every time the info code is changed. The info‐event counter of a new meter will be 0 as transport state prevents counting during transportation. Info logger If you activate the secondary key again, the info code data logger is displayed. The first display reading states the date of the latest info code change. The next activation of the secondary key displays the info code from the above date. Repeated activations of the secondary key alternately induce dates and corresponding info codes. The data logger saves the latest 50 changes (all 50 changes can be displayed) and the rest can be displayed by means of METERTOOL HCW. Note: The info code is saved in the meter’s data logger too for diagnostic purposes. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 86 ...
Transport state means: No info codes are saved in the meter’s logger and the info‐event counter is not active. A power saving measuring sequence is used. SETUP loop is accessible, which enables you to configure the meter before commissioning. Note: In general SETUP loop is available, it can however be limited by the selected country code. Please be aware that the access to SETUP loop will be blocked and the meter will leave transport mode if the configuration in SETUP loop is ended by the function EndSetup. When the meter has left transport state info codes will be logged and the measuring sequence is changed to the one ordered for the meter (determined by the L‐code). The meter cannot revert to transport state, unless a total reset is made. The access to SETUP loop can, however, be opened again by separating calculator top and base, this means breaking the installation seal, see paragraph 4.8. Radio communication On delivery the meter is in transport state and the meter’s radio communication is deactivated. The radio is activated by the first integration the meter carries out. In transport state and after commissioning of the meter the radio can be enabled either via SETUP loop or by making a forced dial‐up (both front keys are activated until ”CALL” is displayed). Enabling the radio does not cause the meter to leave transport state. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 87 ...

It is possible to data read the latest 50 changes of the information code as well as the dates the changes were made. When the information code is read from the display, the latest 50 changes including dates can be read. All of the 50 changes can also be read by means of the PC program LogView HCW. Info event Every change of a parameter of the info code results in an info event if the selected country code is configured with the parameter. It is therefore not certain that all parameters result in an info event. An info event results in accumulation of the info event counter as well as logging in the info logger. This does not apply whilst the meter is in transport state or if the calculator top and base are physically separated. Reconfiguration of active parameters of the info code will influence future info codes, whereas all logged info codes remain as they were at the time of logging. 7.9.2 Config logger Every time the configuration is changed, the below‐mentioned register types are logged. Thus, it is possible to data read the latest 25 changes of the config log as well as the date the change was made. The meter permits only 25 changes, unless you break the legal seal and carry out a total reset of the meter, which also resets the config log. Note: The 25 change of configuration must be carried out on the installation site, i.e. either via SETUP loop or via METERTOOL HCW.

, can be omitted and the formula reduced as follows: Thus, we know the basic connection between the average flow velocity and the transit time difference. The transit time difference in a flow sensor is very small (nanoseconds). Therefore, the time difference is measured as a phase difference between the two 1 MHz sound signals in order to obtain the necessary accuracy. Furthermore, MULTICAL® 403 takes the influence of the temperature of the water into account i.e. the built‐in ASIC uses the sound velocity at the water’s current temperature in connection with the flow calculations. The flow (volume flow rate) is then determined by measuring the transit time difference, calculate the average flow velocity and multiply it by the area of the measuring tube: where: is the flow (volume flow rate) Is the area of the measuring pipe The volume V passing through is finally calculated as a time integration over the flow (multiplication of (cross section constant) flow by time).

In practice the highest possible water flow through the meter will be limited by the pressure in the system or by possible cavitation due to too low back pressure. If the flow is lower than min. cut‐off or negative, MULTICAL® 403 does not measure any flow. According to EN 1434 the upper flow limit q is the highest flow at which the flow sensor may operate for short periods of time (1 h/day, 200 h/year) without exceeding max. permissible error. MULTICAL® 403 has no functional limitations during the operating period above q . Please note, however, that high flow velocities may cause cavitation, especially at low static pressure.

Installation of mains connected equipment for registration of consumption. (www.sik.dk, SIK‐message Electrical Installations 27/09, February 2009) The consumption of energy and resources (electricity, heat, gas and water) of the individual consumer is to an increasing extent registered by electronic meters, and often equipment for remote reading and remote control of both electronic and non‐electronic meters is used. General regulations for carrying out installations must be observed. However, the following modifications are permitted: If meter or equipment for remote reading or remote control is double insulated, it is not necessary to extend the protective conductor to the connection point. This also applies if the connection point is a plug socket, provided that it is placed in a canning which is sealable or can be opened with key or tool only. If meter or equipment used for remote reading and remote control is connected to a safety transformer mounted in the panel and direct connected to the branch conductor, no on‐off‐switch or separate overcurrent protection in either primary or secondary circuit is required, provided that the following conditions are fulfilled: The safety transformer must either be inherently short‐circuit‐proof or fail‐safe. The conductor of the primary circuit must either be short‐circuit‐protected by the overcurrent protection of the branch conductor or short‐circuit safely run. The conductor of the secondary circuit must have a cross section of at least 0.5 mm² and a current value which exceeds the absolute maximum current deliverable by the transformer. It must be possible to separate the secondary circuit, either by separators, or it must appear from the installation instructions that the secondary circuit can be disconnected at the transformer’s terminals. General information Work on the fixed installation, including any intervention in the group panel, must be carried out by an authorized electrician. It is not required that service work on equipment comprised by this message as well as connection and disconnection of the equipment outside the panel is carried out by an authorized electrician. These tasks can also be carried out by persons or companies, who professionally produce, repair or maintain equipment if only the person carrying out the work has the necessary expert knowledge.

Thus, modules with e.g. M‐Bus interface use the KMP protocol internally and the M‐Bus protocol externally. Integrity and authenticity of data All data parameters include type, measuring unit, scaling factor and CRC16 check sum. Every produced meter includes a unique identification number. 12.2 Optical eye The optical eye can be used for data communication via the optical interface. The optical eye is placed on the front of the calculator just above the IR‐diode as shown in the picture below. Please note that the optical eye includes a very strong magnet, which should be protected by means of an iron disc when not in use. Various variants of the optical eye appear from the list of accessories (see paragraph 3.2.1). Power‐saving in connection with the optical eye 12.2.1 In order to limit the power consumption of the circuit around the IR‐diode, the meter includes a magnet sensor which switches off the circuit when there is no magnet near it. 12.3 Data protocol Utilities and other relevant companies who want to develop their own communication driver for the KMP protocol can order a demonstration program in C# (.net based) as well as a detailed protocol description (in English language).

13 Test and calibration MULTICAL® 403 can be tested as a complete energy meter or as a split meter depending on the available equipment. The high‐resolution test registers are read from the display, via serial data reading or via high‐resolution pulses. Before test as a split meter, disassemble the meter and screw off the sensor pair. Subsequently, the calculator is tested separately by means of Kamstrup calibration equipment for MC403 and METERTOOL HCW. Flow sensor and temperature sensors are tested separately too. During test of the flow sensor it is unimportant whether the temperature sensors are mounted. For fast test/calibration of MULTICAL® 403, the meter has a test mode with an extra fast measuring sequence. In test mode heat energy, cooling energy and volume are displayed with higher resolution than normal in order to shorten ...
Pulse_select Pulse input or pulse output selector 13.3 Test The following paragraph briefly describes the various functions used during test. The description is divided into flow test and calculator test. 13.3.1 Test of flow sensor The high‐resolution volume can be accessed through the serial interface or by reading the display. Is used during both standing and flying start/stop. 13.3.2 Test of calculator The calculator supports autointegration, which is used for testing the accuracy of the temperature measurement. Autointegration counts a simulated volume over a given number of integrations with an evenly distributed increase of volume. At each integration, the temperature of the temperature sensors is measured and with the simulated increase in volume, energy is calculated. The energy and an average of the temperature measurement can subsequently be read either from the display or through serial communication. Autointegration can be started via the serial interface. Further, it can be activated by a keystroke when the meter has been legally unlocked. If the meter has not been unlocked, autointegration can be used, but it does not increment volume and energy in the legal registers. However, this requires that the installation seal is broken. Used in connection with standing start/stop. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 116 ...

Screenshot to be added here 14.3.6 Data logger reset Reset of the calculator’s programmable data logger, which influences yearly, monthly, daily and hourly loggers as well as the info code log. The configuration log is not reset. 14.4 Autointegration By means of the function autointegration the meter can be tested and verified. During autointegration you must either connect known precision resistors to the meter’s temperature sensor inputs or place the temperature sensors in precisely controlled baths. Thus, you can simulate energy consumption and verify the meter’s energy calculation. Autointegration counts in two separate high‐resolution autointegration energy registers (”E1HighRes_autoint” and ”E3HighRes_autoint”), depending on energy type. These registers are reset after each autointegration. To be able to carry out an autointegration it is necessary to break the installation seal and separate the calculator top and bottom, see paragraph 4.8 for further information on sealing and paragraph 6.3 re SETUP loop. An autointegration can always be carried out by separating calculator top and base, even if the config log is full (i.e. 25 times). Note: Autointegration does not influence the legal registers E1 and E3. Kamstrup A/S ∙ Technical description ∙ 5512‐1689_B1_GB_03.2017 126 ...
The calibration result of each test point is stated in percentage and can be saved in the computer under the serial number of the tested MULTICAL® 403. Subsequently a test certificate can be printed. 15.3 Calibration data The first time METERTOOL HCW and the calibration equipment are used, a number of calibration data must be entered. This is done via the menu ”Adjust calibration unit” in METERTOOL HCW.
