Control options for MTRE pumps
Communication with MTRE pumps is possible by
means of

and control the pressure, temperature, flow or liquid
level of the system.

External control signals
Communication with the MTRE pump is possible even
though the operator is not present near the MTRE
pump. Communication is enabled by connecting the
MTRE pump to an external control or monitoring
system allowing the operator to monitor and change
control modes and setpoint settings of the MTRE pump.
