Water storage tanks require regular monitoring to prevent overflow, dry running, and water wastage. Manually checking the water level is time-consuming and inefficient.
An automatic water level controller solves this problem by automatically controlling the pump based on the tank level. It improves efficiency, protects the pump, and reduces manual effort.
By installing a water level controller, System get automatic for drainage & filling purposes. This Can also be used in saving the submersibles or pumps from dry run & Overflow conditions.
WATER LEVEL CONTROLLER
“Water level controllers are electronic devices Which continuously monitors the water level present in the tank. When level of water crosses the particular level inside the tank, It produces an electrical signal.”
There are different types of water level controllers but in this post we will explain water controller made by L&T.
This controller generally contains 3 steel probes which get immersed inside the water. Controller continuously monitors resistance in between the probes. These steel probes are just a thick conductor which is having a larger surface area.
When all the probe get dipped inside the water, resistance value get lowered in between them. While without water; resistance get higher !
According to the resistance value, Controller changes its changeover contacts which can be used to get the signal or to control the water pump.

Applications of L&T water level controller XM810550000
FOR TANK FILLING
“Tank filling consists of filling the tank until it get filled, After complete filling pump get switched off. “
