The GE-315 Series Target Water Flow Switch is a new type flow switch, avoilding rust and bad contact by separating the electricity from the liquid. This products totally give up the isolating part for water and electricity by corrugated pipe applied on common target flow switch. When the micro switch is operating, it won’t touch with low temperature metal part, so no condensation water, no rust and bad contact, and the Protection Grade up to IP65, it could be applied in corrosive air environment.
Similar as Sika & Honsberg Flow Switch, but cheap price.

* NPT or other thread is available
* The adjustable range is for flow setpoint, not for max flow rate.
* When choose the products, tell us the model number, adjustable range, the wire connection. (if you have special demand, you could tell us too, we could custom-made OEM & ODM for you specially)
