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

Applications requiring a constantly monitored flow of cooling or cleaning water now have the perfect solution with the launch of the new PF3W Digital Flow Switch Series from the world leaders in pneumatics - SMC. Developed following the success of SMC’s PF2W flow switch range, their R&D engineers have now taken these flow switches to a new level by improving both their design and operating performance
