Hydrostatic Systems

Hydrostatic Systems

These employ a Pressure Transducer or Transmitter which when placed in a liquid, measures the pressure. Changes in the pressure reflect changes in depth so that a continuous indication of level is obt...

Float Systems

Float Systems

A small magnetic float slides on a tubular shaft in which reed switches are mounted at intervals. The float follows the rise and fall of the liquid and actuates the switches to produce a continuous le...
