Feature

●Flow control value is adjustable, repeat action point is stable.
●It is used to measure the dynamic state of the liquid flowing through the pipeline, such as: water, ethylene, ethylene glycol and other liquids that have no corrosive effect on copper.
●Protection grade is IP54, the micro switch contact life is up to 100,000 times
●When flow rate exceeds set value, fluid drives blade and micro switch, the SPDT contact can connect a circuit and disconnect other circuit.
●Perfect for water treatment system, central air conditioning, water cooling unit.
