Proteus flow switches monitor cooling flow and other liquids in industrial applications. The 100 and 1000 Series are purely flow switches, while the 500 and 800 Series include metering outputs.

Our flow switches are backed by our five-year warranty. We have additional information for international customers.

Free samples are available for qualified OEMs.

We also offer flow meters and the WeldSaver™ for robotic welders.
