Flow Switches – PF3

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, these switches incorporate a built-in temperature sensor so both flow and fluid temperature can be effectively monitored at the same time.  Further improvements include the addition of 2 screens, incorporating 3-color numerical displays which can also be rotated in both clockwise and counter-clockwise directions, thereby offering even better display visibility during operation.  Available as non-grease type and with analogue output if required, the PF3W meets IP 65 enclosure protection standards and is both RoHS and CE compliant.
