Series PF3W digital flow switch is perfect for applications requiring a constantly monitored flow of cooling or cleaning water. The PF3W series has been improved both in design and operating performance over the PF2W flow switch.  Depending on the selected model, the PF3W is up to 40% smaller in volume, offering improved piping space and flexibility.  Designed to work with fluids up to 90ºC

PF3W is a digital flow sensor that constantly monitors water or coolant flow.  PF3W refreshes the design and operating performance of the legacy PF2W model.  The body is up to 40% smaller in volume, and requires shorter straight piping for improved installation flexibility.  The upgraded 2-screen, 3-color numerical display rotates in both CW and CCW directions, offering improved visibility
