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 90

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.  This is the remote version of PF3W7, with a display.  One or two analog outputs are available, depending on whether the optional temperature sensor is selected.  Additional options include a mounting bracket, flow adjustment valve and
