!
Note!
Only one temperature available for liquid heat quantity. A direction signal teriminal is required on
changing flow direction (bi-directional operating mode).
Steam application
Input values: Flow, pressure, temperature 1, (temperature 2)
!
Note!
2 temperature sensors are required for steam diferential applications.
Pressure
Select signal type and terminals and then connect sensor (see example).
Type: Relative- or absolute-pressure? Enter start- and end-values.
Temperature
Select signal type and connect sensor(s) (see example). 2 temperature sensors are required for heat differential measurements.
Application
Application: e.g. Water- heat differential
Operating mode: e.g. heating (this means inflow warm, return cold)
Allocate installation point for flow measurement sensor (warm/cold)
Allocate temperature sensors
