Series GFM2 Gas Mass Flow Meter
Brand: Dwyer Instruments, LLCThe Series GFM2 Gas Mass Flow Meters is an ideal choice for the measurement of flow rates of a wide variety of gases.
Unit can be calibrated for a variety of gases with user selectable 0 to 5 Vdc or 4 to 20 mA and two relay outputs and programmable totalizer that indicates total gas quantity.
Features- Utilizes a straight tube sensor with a restrictor flow element to provide a high ±1% Full Scale accuracy and ±0.25% Full Scale repeatability
- Gas flow can be displayed in 23 different engineering units on an optional 2x16 character LCD display with internal conversion factors for up to 32 gases
- Digital RS-232 or RS-485 interfaces allow for easy communication and for multi-drop capability of up to 256 units (RS-485 only)
- User-friendly interface allows for the programming of high and low gas flow alarms, along with two user-programmable electromechanical SPDT relays with latch options
- Stores calibration information for up to 10 different gases, internal or user-specific K-factors
- Automatic sensor zero offset adjustment (via digital interface or local push button)
- NIST traceable certificate included
- Self-diagnostic tests
