Providing ±1% FS accuracy and ±0.25% FS repeatability, Series GFM2, GFM3, and GFM4 can store calibration information for up to 10 flow gases. Digital RS-232 or RS-485 interfaces allow for communication and for multi-drop capability of up to 256 units (RS-485 only). Additionally, interface allows user to set alarms remotely to alert when high/low flow thresholds are exceeded. With self-diagnostics running at start up, GFM2, GFM3, and GFM4 offer optimal choice in gas flow metering/monitoring.
