Heat statement
■ Statement:
Through determining the temperature
differential between the flow and

captured by the flow meter.
■ Sensor inputs S1 and S10 to S12 are
provided in the delivered condition for
this purpose.
Should the flow temperature sensor
have to be located at a point where
temperatures in excess of 90 °C could
occur, always connect it at S1 or S9
