MULTICAL® 402
Energy Measurement
MULTICAL® 402 functions in the following way:
The flow meter registers the amount of district heating water in
m³ (cubic metres) circulating through the heating system.
The temperature sensors placed in inlet and outlet pipes
register the cooling, i.e. the difference between input and
output temperatures.
MULTICAL® 402 calculates consumed energy based on volume
of district heating water and cooling.
Readings
When the top front key is activated, a new reading
appears.
The lower front key displays historical readings and
average values.
Four min. after the latest activation of the front key the meter
automatically switches to consumed energy.
