ZHFS FLOW SWITCH
Specifications
HFS Liquid Switches are Single-Pole-Double-Throw(SPDT) flow switches that are used in liquid lines carrying water, ethylene glycol, or other liquid not classified as hazardous. They can be wired to energize one device or powered from the same source when liquid flow either exceeds or drops below the set flow rate.
The rate of the flow can be adjustable and it is stable
Liquid temperature range: 0~+100
Max. Working Pressure: 13.5bar
Flow switch can not be used where the liquid in the pipes will drop below the liquid's freezing point
