Float Level Controller

Sump and sewage float switches have a float that raises and lowers depending on the water level in the sump basin to automatically control switch operation.

Float level controller.

A contractor was called on to come up with a solution for their customer needing to transfer an adhesive from a holding tank to a smaller tank for dispensing into containers. We supply a diverse range of industries including. Liquid adhesive level application. The problem with using a conventional float type level sensor is that the adhesive would cause the float switch read more.

A non magnetic barrier tube effectively isolates the switch mechanisms from the controlled liquid. Click to enlarge above shows an example of a custom multi level float switch like the m5002 set for pump up control. When water rises to a preset level in the sump basin the switch turns on and the pump starts. As the float rises or falls with liquid level it moves a magnetic sleeve into or out of the field of a switch actuating magnet causing switch operation.

This cycle will automatically repeat once the level rises. Once the fluid reaches the low level the lower float switch will open and the controller will remove power from the pump or valve automatically. When the water is drained down the switch turns off and the pump stops. The proposed water level controller circuit using a float switch is basically a semi automatic system where the pump is started manually by press of a button once the water level reaches the brim of the tank the operation is switched of automatically by means of a float switch.
