Double pump – closed loop control
3.2.1
Closed loop control non redundant: differential pressure with PumpMeter (Modbus) –
typical application
Etaline Z double pump (2x100%): A constant differential pressure of 4 bar is needed. PumpMeter is used as a differential pressure sensor
in the measurement range of -1 … 10 bar. PumpMeter is connected by Modbus to the M12 Module of the drive. The set point is given by
the display. Pump changeover will take place regularly after 24 hours of operation.
