This level sensor & water level controller is designed to On/Off the water pump i.e. If your application is to start the water pump at low level / stop at high level i auto mode and if you want Buzzer sound at the empty of water tank in mid level, then this 'PRECISION' make water level controller is one of the best Automation Controller for your application. If your low level is completed and pump get start, increases to certain level, if then you need to stop the water pump manually, you can Off it. Between low level and high level, pump can be start / off manually. while draining the water tank when it reaches mid level going donwards, you will get the alert sound from the Buzzer signally mid level in controller, By push button you can reset the Buzzer and when it comes in low level, then pump will start in auto. Between Low level & High level if power fails, when power comes back you can start the pump manually from the level only no need to wait for complete drain of the water from the tank.

Dual Magnet Horizontal Mounting Float Switch
Principle of operation : Precision make model PMLS magnetic level switches work on principle of magnetic repulsion and therefore they are glendless and leak proof instruments. A permanent magnet fitted in the tail piece of the float repels another magnet inside the switch housing which in turn operates an SPDT micro switch. Micro switch contacts can be utilized for initiating audio-visual signals or pump control.

Caution

• Level switches should not be used for direct starting / stopping of pumps. An external relay or contactor must always be used with the level switch.
• PMLS side mounted level switches must always be mounted horizontally with outgoing cable entry.
