  • The Series GFM3 Gas Mass Flow Meter is an ideal choice for the measurement of flow rates of a wide variety of gases. This digital flow meter features a 12-digit totalizer for total gas volume indication, and is available in the choice of 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA output signals. Standard LCD and four button keypad allows easy access to the many features of the GFM3. Digital interface operates through available RS-485 or RS-232, providing access to internal data parameters and multi-drop capability of up to 255 units (RS-485 only). Set alarms remotely via digital interface for flow to alert user of high or low thresholds being exceeded. With a high ±1% FS accuracy and ±0.25% FS repeatability, the GFM3 is the optimal choice in gas flow metering and monitoring. The GFM3 comes with a NIST traceable certificate.
