✔ Application - This flow switch is an automatic element that controls flow in pipes, which can be used on water treatment system, central air-conditioning, water cooled chiller and relative industries..
✔ Measure Range - It is used to measure the dynamic state of the liquid flowing through the pipeline. Applicable fluid includes water, ethylene glycol, oil or other liquid not classified as hazardous or corrosive and air..
✔ Adjustable - The flow control value is adjustable and the action repetition point is stable..
✔ Automatic Control - When flow rate exceeds set value, fluid drives blade and micro switch, the SPDT contact can connect a circuit and disconnect other circuit..
