SMC PFM725-N7-E-W 2-Color Digital Flow Switch For Air

PFM7 is a digital flow sensor compatible with air, nitrogen, argon and carbon dioxide. This is a legacy sensor, refreshed in 2019 as PF2M7. The 3-digit LED display can be red or green, changing when a set point is reached. Either instantaneous or accumulated flow can be shown. Options include inline or bottom piping entry, cable connector type, a manual flow adjustment valve, and panel or bracket mounts. Two outputs are available, including two switch signals, or a switch and analog signal. PFM7 is IP40 rated, and C-UL-US and CE compliant. See PF2M7 if RoHS is required.
