Air flow sensor monitors with digital displays to mount in a panel or near an operator's station.

PFG3, Digital Flow Monitor, 3-Screen 3-Color, IP40, for PFMB or PFM sensors
PFG3 is a monitor with display for the PFMB or PFM flow sensor. This model improves upon SMC's legacy monitors with the 3-screen 3-color display, as well as adding a 0-10V output. View the sensor's measured value in the primary screen, while viewing a variety of secondary data in the sub-screens, including switch set point values, and accumulation quantity, or a peak or bottom value. Alternately, assign a text description for the sensor's line or location. While primarily suited for pairing with a flow sensor (displayed units are L/min or CFM), the range input function can scale the connected sensor's analog output signal to any range desired. This enables the monitor to be used with many other sensor types, such as pressure or temperature sensors. PFG3 is IP40 rated, and CE and RoHS compliant.
- 9 selectable flow ranges, plus custom user ranges
- Analog input, sensor (DC): 1-5V or 4-20mA
- Analog output, monitor (DC): 0-10V, 1-5V or 4-20mA
- Switch ouput modes: Hysteresis, window comparator, accumulation set point, accumulation pulse, error, and OFF
- Display accuracy: ±0.5% F.S.
- Analog output accuracy: ±0.3% F.S.

PFMV3, Digital Flow Monitor, 2-Color Display, IP40, for PFMV5 Sensors
PFMV3 is a monitor with display for the PFMV5 remote flow sensors. The sensor and monitor can be located up to 2m apart using the optional cable. 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. An extensive range of function settings influence performance, power saving and security as well as core flow monitoring tasks. 2 NPN or PNP switch outputs are included, with an LED indicator for each, located below the display. An analog output is also included. A cable, mounting bracket and panel mount adapter are optional. PFMV3 is IP40 rated, and C-UL-US, CE and RoHS compliant.
- Flow ranges (lpm): 0-0.5, 0-1.0, 0-3.0, -0.5-0.5, -1.0-1.0, -3.0-3.0 (selectable from PFMV5)
- Analog input, sensor (DC): 1-5V
- Analog output, monitor (DC): 1-5V or 4-20mA
- Switch output modes: Hysteresis, window comparator, accumulation set point, accumulation pulse
- Display accuracy: ±0.5% F.S.
- Analog output accuracy: ±1% F.S.
