Floin Valves And Instruments

Top Mounted  Level Switch is monitors the liquid level in a tank and sends a trip signal to another device such as a Pump to protect it. These Level Switches are used for Pump protection, Cooling Circuit protection, high & low level signal and general level monitoring. 

Side mounted level switch float mounted at one end of connecting rod moves with change in level, magnetic capsule at other end of rod moves accordingly within fixed limits Switch contacts across the face change accordingly.
As the tank fills up the float lifts up due to buoyancy. The other end of the float which is magnetic in nature goes down and during its downward motion, triggers the switch assembly and the contacts get closed, which can be used to operate an alarm or any other audio/visual load.
