Trevoli – Sewage Pump Controller

 L932-S  L922-S_Components


This pump controller can control one or two single or three phase pumps.

It features a level transmitter which removes the need for float switches and level sensors. The level transmitter is attached to the top end of a pipe inside the sewage tank. As the liquid level rises, the pressure inside the pipe increases – this pressure change allows the controller to know the liquid level. This removes the need for regular cleaning and checking of float switches and level sensors.

Comes with a remote monitor which allows monitoring and controlling the pump from up to 1200m distance from the controller.
