Features:
It is used to measure the dynamic state of the fluid flowing through the pipeline. For example, water, ethylene, ethylene glycol and other liquids that do not corrode on copper.
When the flow rate exceeds the set value, the fluid will drive the blade and micro switch, and the SPDT contacts connect the circuit, and the other circuits can be cut off.
The flow control values are adjustable and the repeat operating point is stable.
IP54 protection rating, up to 100,000 touches on the micro switch
Ideal for water treatment systems, central air conditioning and water cooling units
