4.4.3 Dosing control (Flow Monitor)
The pressure sensor (Flow Monitor pump option) is used as a
dosing controller and to monitor the pressure for the whole power
ranges.
The Flow Monitor for dosing control consists of a pressure sensor
integrated in the dosing head.
The pressure sensor is available as Flow Monitor pump option.
The pressure sensor is fitted to the pump on delivery. Upgrades
are not possible.
4.4.4 Flow compensation
The flow compensation is a function to keep the dosing flow
constant with changing system pressure. Pressure changes are
detected by the pressure sensor and the motor speed is adjusted
accordingly.
To use this function, pressure control or dosing control (Flow
Monitor) has to be activated in the electronics.

Pressure control is primarily used to protect the
pump. This function is not a substitute for the
overflow valve.
When dosing media with a viscosity similar to water,
the pump needs not to be calibrated, as the pump
already responds to the possible change of the
system pressure.
When dosing media with a viscosity different from
water or after a software update, the pump has to be
calibrated.
