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 in a range of orientations. Two outputs are available, including two switch signals, or a switch and analog signal. Options include a mounting bracket, flow adjustment valve and temperature sensor to monitor flow and temperature simultaneously. PF3W is grease-free, IP65 rated, and C-UL-US, CE and RoHS compliant.
