PF2A3 is a monitor with display for the PF2A5 remote flow sensors. The sensor and monitor can be located up to 3m apart using PF2A5's optional cable. The red 3-digit LED display can show instantaneous or accumulated flow. 2 NPN or PNP switch outputs are included, with an LED indicator for each, located below the display. Units can be switched between L/min or CFM (flow), and L or ft³ (accumulation). A key lockout function can prevent accidental setting changes during operation. A panel mount adapter is standard. PF2A3 is IP40 rated, and CE and RoHS compliant.
