Flush tube and flush valve
The flush tube contains a nozzle ring that sprays cleaning water around the sensor and cable.
Each time the sensor moves upwards into the flush tube, the cleaning works until the sensor
reaches its highest position ("home position"). In that way the sensor keeps clean and the
measurement is reliable in most environments and processes.
In the home position the sensor is completely covered by the flush tube, which contains an
inductive limit switch. The switch determines the point when the sensor reaches its home
position.
Flushing starts when the built-in solenoid flush valve opens. Its control is the task of the main
electronics unit.
