Proteus Flow Switches monitor cooling fluids and other liquid flows and trip an internal relay if the flow rate falls below an adjustable trip point flow. The relay can be used to shut down a system or process or to sound an alarm before damage is done to valuable equipment and products.

Fail-Safe System Protection

Unlike pressure activated sensors, the Proteus flow switch provides a true flow interlock – it will not be fooled by down-stream blockages that maintain pressure while stopping flow. And unlike simple paddle- or vane-activated devices, particle buildup cannot jam the mechanism in the 'Flow OK' position.

The traditional Proteus active design combats the problem of particle buildup that can jam many other flow switch types. Because the rotor is constantly spinning, it clears itself of most buildup. In the unlikely event that a large object in the line interferes with the rotor, the rotor stops turning and the switch goes to its alarm condition.

When a Proteus flow switch shows fluid is flowing, there is ALWAYS fluid flowing through the switch
