The Hydromatic The HPLC can be placed in virtually any liquid storage or holding tank to control liquid levels including larger sump basins, sewage basins and lift stations, cisterns, septic tanks, clear water storage tanks, solution tanks, bulk tanks and more.

The housing remains stationary while a pressure activated, rolling diaphragm drives a piston throughout a series of micro switches. These are held in a unique switch track located in the head of the LCS housing. The track can hold up to 14 switches for starting and stopping pumps, activating high or low level and audible alarms, and controlling various other features.
