i need to know the calculation equation for that system based on the data which is given by the meter like T1 and T2and actual flow with accumulated volume as i have one meter like that but the reading i think it is not right so how i calibrate the reading or make some calculation to know the error

The Kamstrup MULTICAL 602 system calculates power using the equation:
P = q (T1 – T2) × k [kW or MW]
Where: - P = Power - q = Actual water flow (e.g., in l/h) - T1 = Temperature at the inlet - T2 = Temperature at the outlet - k = Water's heat coefficient, calculated according to EN 1434:2007
To check for errors in the readings, compare the measured actual flow q and accumulated volume-based average temperatures E8 and E9. E8 and E9 accumulate the product of m³ × °C, which helps verify consistency over time if the volume register is read simultaneously.

1. General information Read this guide before installing the meter. Kamstrup's guarantee obligations do not apply in case of incorrect mounting. Please note that the following installation conditions must be obeyed: - Pressure stage ULTRAFLOW®: PN16/PN25/PN40, see marking. Flow sensor marking does not apply to enclosed accessories.
A/S can, furthermore, supply R½ and R¾ brass nipples fitting the short direct sensors. The short direct sensor can also be fitted directly into all Kamstrup's ULTRAFLOW® variants with G¾ and G1 thread on the meter case. Fasten the sensors' brass unions lightly (approx.

(approx. 3.65 V). Therefore, it is not possible to determine the remaining capacity of the battery by measuring the voltage. The battery cannot and must not be charged and must not be short-circuited. Used batteries must be handed in for approved destruction, e.g. at Kamstrup A/S.
Mains modules The modules are protection class II. They are connected by means of a two-wire cable (without earth) through the cable bush of the calculator placed in the right side of the connecting base. Use connecting cable with 5-10 mm outer diameter and ensure correct dismantling as well as correct mounting of cable relief.
8. Information codes ”InFO” MULTICAL® 602 constantly monitors a number of important functions. In case of a serious error in measuring system or installation, "INFO" is displayed and an info-code can be read by activating the top front key until the measuring unit says "INFO".
The pulse inputs can be used for connection of electricity and water meters. Please pay attention to maximum pulse frequency as well as correct pulse coding (l/imp. and Wh/imp.), which is selected by means of the FF and GG configuration. 65 - 66 Input A 67 - 68...
Wireless M-Bus, type 67-00-30 The radio module has been designed to form part of the hand-held Wireless M-Bus Reader systems of Kamstrup A/S at license-free radio frequency (868 MHz). The module fulfils the C-mode specifications of prEN13757-4 and can thus form part of other systems using Wireless M-Bus C-mode communication.
9.1.13 High-Power RadioRouter + 2 pulse inputs (VA, VB), type 602-00-84 The High-Power RadioRouter module has built-in router functionality and is thus optimized to form part of a Kamstrup radio network, the read data being automatically transferred to system software via the network unit RF Concentrator.
Top modules Type 67-02: DEnergy calculation and hourly data logger This top module calculates the difference between forward and return energy, whereby an expression of the tapped energy in open systems is obtained. Differential energy dE=E4-E5. The module also includes an hourly data logger. The connection terminals of this module are not used.

The RTC and pulse output functions of this top module are identical with the functions described for top module 602-0C (see below). The top module is prepared for use in a Kamstrup radio network together with High Power RadioRouter base module 6020084, read data being transferred to the system software via the network unit RF Concentrator.
