Description

Liquid Level Controller

Simple device, no CPU - only simple logic. If the water level exceeds the first level, the main pump starts. If she can pump out the excess water, the pump stops. If one pump fails and the water level exceeds the water level - the next pump starts and they pump together until they reach a safe level.

All electronics powered from 230V and gives direct output via SSR relay or to terminals if you want to turn on more powerful pumps.
