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.
