Flow Transmitters for Water

Send flow-rate readings to data recorders, loggers, and displays.

Transmitters with a 316 stainless steel body are more corrosion resistant than transmitters with a brass or polypropylene body.

Flow Switches with Indicator for Water

For flow monitoring at a glance, these switches have a plastic window with a rotor indicator that spins when flow is present. They activate or deactivate equipment when the flow rate reaches your set point. All have an adjustment screw for altering the set point to suit your application. Switches are single pole, double throw (SPDT) and can be installed to turn one circuit from "off" to "on" (normally open) or from "on" to "off" (normally closed).

Switches with a polypropylene body are lighter than sights with a metal body.

Switches with a 316 stainless steel body are more corrosion resistant than switches with a brass body.
