MULTICAL

403 operates with 6 different energy formulas; E1, E3, E8, E9, A1 and A2, which are all calculated in
parallel at every integration no matter how the meter is configured. E8 and E9 are used as a basis for the calculation
of average temperatures of inlet and outlet, whereas E1 and E3 are used for heat and cooling measurement
respectively. A1 and A2 are used as a basis for discount/addition, based on the outlet temperature (see paragraph
7.1.3).
7.1.1 Heat/cooling energy registers E1 and E3
Energy types E1 and E3 are described by application examples below.
403-Wxx2
Application A
Closed heating system with one flow sensor
Heat energy: E1 = V1(t1-t2)k
t1:inlet or t2:outlet
Flow sensor V1 is mounted in inlet or outlet as selected
during config.
(Heat meter with MID marking and
Pt500 sensor inputs)
403-Txx5
Application B
Closed cooling system with one flow sensor
Cooling energy: E3 = V1 (t2-t1)k
t1:inlet or t2:outlet
Flow sensor V1 is mounted in inlet or outlet as selected
during config.
(Cooling meter with condensation protection and
Pt500 sensor inputs)
403-Txx6
Application C
Closed heat/cooling system with one flow sensor
Heat energy: E1 = V1(t1-t2)k
t1:inlet or t2:outlet
Cooling energy: E3 = V1 (t2-t1)k
t1:inlet or t2:outlet
Flow sensor V1 is mounted in inlet or outlet as selected
during config.
