Automatic Water Level Controller Connection

What is Water Level Controller,


This controller is normally using in homes and industries for overhead tank water filling.

 An automatic water level controller can auto starting and stop for Submersible pumps and normal pump motors. This fully automatic water level sensor controller direct working in Single phase only (230 V AC). We can auto ON and Off of 3 phase pump motors also with some modification in motor control panel. The water level device's can easily connect into the control circuit of 3 phase Motor Control Panel (MCP) where using heavy contactor.

Automatic water level controller getting different types and different models for motor starters from various manufacturers. We have made and explain many videos for fully automatic water level controller connection on our YouTube channel.

Two types controller available in the market in various price. Fully Automatic water level controller price depends upon your Pump Motor load (KW or HP).

 Water Level Controller Sensor Connection 

This fully automatic water level controller using in submersible motor which required auto starting torque with starting capacitor. So, this type starters are available additional NO point (C1 and C2) as you can see in the picture. The C1 and C2 points are to connect across with the start push button of the motor control panel. Not need to use this connection for direct starter.
