HDP88 Differential Pressure Control HDP88JA Float differential pressure control HDP88W adjustable setting  differential pressure control HDP 98 differential pressure control

This switch is a single pole double throw (SPDT) flow switch which can be used as the relay to measure and observe liquid flow rate. It is usually used for water supply equipment. When the water pump is operating normally, the differential pressure of inlet or outlet is jarless when the load is invariables. While the differential pressure of pump in inlet or outlet is measured for high, whether water was flow across the pump (whether the pump is working) can be judged. Installation a differential pressure type flow switch with a proper setting value, the condition of pump can be known.
