PF2M7, Digital Flow Switch

PF2M7 is a digital flow sensor compatible with air, nitrogen, argon or carbon dioxide.  PF2M7 refreshes the legacy PFM7 with several enhancements.  The thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage.  Dimensions and weight have been reduced, especially beneficial when installed on moving tooling.  Finally, current consumption has been reduced by 36%.  The LCD 4-digit display can be red or green, changing when a set point is reached.  Options include cable connector type, a manual flow adjustment valve, and panel or bracket mounts.  Push to connect fittings align tubing in a straight configuration.  Two outputs are available, including two switch signals, or a switch and analog signal.  PF2M7 is IP40 rated, and meets RoHS and CE standards.
