Designed mostly for water flow monitoring. The differential pressure switch closes or diverts an electric contact when the differential pressure between the two inlets reaches the upper setpoint and opens or releases the contact when it drops below the lower setpoint. A typical application would be to mount differential pressure switch across the condenser vessel of a water source package air conditioning unit to prove water flow. When connected across a venturi can be used to detect flow in almost any water based application.
