Proteus flow meters monitor cooling flow and other liquids in industrial applications.

Our flow meters 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 switches and the WeldSaver™ cap-loss detector and coolant flow controller for robotic welding systems.
