Rated 1 out of 5 by from Great product! Unacceptable service I have one installed in a housing I made myself, and it has been working perfectly for about a year now.

Rated 3 out of 5 by from Flow Switch service replacements Sensors worked good, Many challenges to overcome for DC power supply, DC relay connections, and additions of DC to AC relays for proper operation

Rated 1 out of 5 by from Documentation sucks I guess these sensors connect themselves because there is ZERO info on the color code and wiring for NPN or PNP. No flow data either?????

How does one set the flow at which the device switches?

Asked by: DavidD
Thank you for your inquiry. There's a potentiometer on the flow switch which you can use to set the switch point. Full instructions to set a switch point can be found in the manual on page 12.

Can this unit be used in a wash down area; is the housing sealed against water ingress?

Asked by: BCB13
Thank you for your inquiry! These sensors have a NEMA 4X rating and should not have any issues in a washdown area.
