The Series GFM2 Gas Mass Flow Meter measures the mass flow rate of gases with high accuracy and stability. Using thermal or other mass-flow sensing technology, it compensates for temperature and pressure changes, giving reliable mass flow readings for industrial gases. Ideal for processes involving gas mixtures, combustion, chemical reactions, or wherever precise gas flow measurement is needed for control, safety or efficiency.

Key Features:

Mass flow measurement of gases (not volumetric) for greater accuracy under variable conditions

Compensation for temperature and pressure changes

High resolution and repeatability for precise control or recording

Robust design suited to industrial gas applications (clean/dry or specific gas compatibility)

Low-pressure drop across the meter

  • Utilizes a straight tube sensor with a restrictor flow element to provide a high ±1% FS accuracy and ±0.25% FS 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
