Flow sensor manufacturers have been working on alternative techniques to replace the mechanical principle. Research and development at Kamstrup has proven that ultrasonic measuring is the most viable solution. Based on microprocessor technology and piezo ceramics, ultrasonic measuring is not only accurate but also reliable.
The area and the length which the signal travels in the sensor are well-known factors. The length which the signal travels can be expressed by , which can also be written as: where: is the measuring distance is the sound propagation velocity is the time Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...
Page 27
To minimize the influence from variations of the velocity of sound in water, the latter is measured via absolute time measurements between the two transducers. These measurements are subsequently in the built-in ASIC converted into the current velocity of sound, which is used in connection with flow calculations.

(Q Please note, however, that high flow velocities > Q (Max flow) involve the risk of cavitation, especially at low static pressures below 0.2 MPa (2 bar) after the meter. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...

PN10 or PN16 connections are used. Kamstrup A/S recommends drinking water approved fibre gaskets for cold water installations. If a non-return valve is installed, it will usually be necessary to use 4 mm PE gaskets instead, to prevent the collar of the coupling from damaging the valve.

In order to facilitate replacement of the meter, closing valves should be mounted on both sides of the meter. Under normal operating conditions no pipe strainer is required in front of the meter. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...
In order to avoid formation of air bubbles or vapor dents in the meter (cavitation) – and to ensure correct measurement under all circumstances – the operating pressure in the pipe installation, immediately after the meter (the downstream), must always be minimum 0.2 MPa (2 bar).

Receiving the Wireless M-bus signal, which is emitted at intervals of 16 or 96 seconds, depending on the meter configuration, alternatively receiving the wired M-Bus datagram • Reading via the optical eye, e.g. by means of Kamstrup A/S’ wireless optical reading head, or optical reading head with USB connector. 16.2 Volume measurement The meter calculates water flow currently according to a fixed measuring cycle.
Logging the minimum flow is a valuable information when tracing excessive consumption from temporary leaks. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...
During periods without water flow the weighted average cannot be calculated and then a code 128 is stored, indicating that there is no consumption. Measuring the water temperature is only valid for meter sizes 1.6, 2.5 and 4.0 m Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...

The Wireless M-Bus signal includes the LEAK code. If the LEAK code is active, or has been active within the latest 30 days, a time indicator with 7 time intervals will indicate how long the info code has been active. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...

In order to avoid false alarms due to short-term air build-up in the meter, the info code DRY is not added to the relevant registers until it has been continuously active for 30 minutes. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...
Page 45
Info code – RADIO OFF (transport mode) This info code is active and flashes in the display when the water meter leaves Kamstrup A/S, and indicates, that the meter is still in ‘transport mode’ and that the built-in Wireless M-Bus radio transmitter has not yet been activated.

+/- 10 %. As long as no adjustments have been made, both the ‘A’ and the digit are inactive, and Kamstrup A/S does not add further adjustment marking to the meter. After the first adjustment, the ‘A’ activates and the digit shows the number of adjustments (1 to 9).
The meter is fitted with an optical eye that gives access to the meter's external interface, with which all the meter's data registers can be read. For instance data can be read using Kamstrup's optical reading head. The reading head includes a permanent magnet which switches on the optical eye.
The loggers are static ones. Thus, the register types cannot be changed. The same applies to the logging intervals. When there is no more space in logger (EEPROM), the newest logging will overwrite the oldest log. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...
For the following modules: 60, 61, 62, 63, 64, 65 and 99 the daily, monthly and yearly loggers are not accessible from the optical eye, which is why the values in the loggers will be cero (showing a ‘0’). Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...
If the meter for example is purchased with module 40, it can be reconfigured to match one of the other modules. In addition to this, the radio can be turned off when needed. Already during the ordering process the desired setting is taken into account. DataTool can be obtained from Kamstrup by sending an e-mail to service@kamstrup.com...
The register size is 2 bytes, apportioned with 4 bits for info codes and 12 bits for the info code hour counters. The distribution is shown below – the numbering shows the bit position. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...

When the meter switches to ‘verification mode’, the wireless M-Bus radio transmitter will be turned off. At the same time a time-out starts. When the time-out period has expired the meter switches back to normal mode. The time-out period is 9 hours. Kamstrup A/S • Technical Description • 5512-1242_N1_GB • 10.2019...
The meter is initially verified from the factory. A new factory adjustment requires disassembling of the meter and can only be carried out by Kamstrup A/S. When the meter has been locked it is only possible to make a percentage correction of the flow curve at three individual points. This is called re-adjustment.
