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
