PumpMeter
Product description
The PumpMeter device is an intelligent pressure sensor for
pumps, with local output of measured values and operating
data.
The device consists of two pressure sensors and a display unit.
It records the load profile of the pump in order to indicate any
potential for optimising energy efficiency and availability.
PumpMeter is supplied completely assembled and
parameterised for the corresponding pump. It is ready for
operation as soon as the M12 plug connector is plugged in.

Product benefits
▪
Transparent pump operation
Local output of the relevant operating data, especially the
operating point of the pump.
▪
Identifies energy saving potentials
by recording and analysing the load profile and displaying
the energy efficiency icon (EFF), if applicable.
▪
Saves time and money
The sensors are fitted to the pump at the factory, unlike
conventional instruments used in systems.
▪
Helps increase pump availability
by recognising and avoiding operation outside of the
intended operating range.
Functions
Pressure transmitter function
The discharge pressure or differential pressure of the pump are
transmitted as a 4-20 mA signal. Connection via the RS485
serial interface with Modbus protocol is also possible.
