The SMC PFM7 series digital flow switch developed initially to detect microchip component adsorption in vacuum and early clogging in both filter and nozzle applications. It is incredibly compact and lightweight compared to existing flow sensors thanks to its micro electro mechanical system (MEMS) sensor. With its unique integrated flow adjustment valve, which can be added or disconnected by simply removing its retaining clip, linear flow rate can be adjusted manually by rotating the flow rate adjustment knob.
