PFM7, Digital Air Flow Sensor, 2-Color Display, IP40, 0.2-100 Lpm

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.
