The Series GFM4 Gas Mass Flow Meter is an ideal choice
for the measurement of flow rates of a wide variety of gases.
This multi parameter flow meter supports various functions
such as flow totalizer, flow, temperature, and pressure alarms,
and is available in a choice of 0 to 5VDC, 0 to 10VDC, or 4 to 20
mA output signals. Standard LCD and four button keypad
allows easy access to the many features of the GFM4. 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, pressure, and temperature to alert
user of high or low thresholds being exceeded. With a high ±1%
FS accuracy and ±0.25% FS repeatability, the GFM4 is the
optimal choice in gas flow metering and monitoring. The GFM4
comes with a NIST traceable certificate.
