The GF868 flare gas flowmeter improves the efficiency of petrochemical plants, refineries and offshore platforms. It uses a proprietary algorithm to determine instantaneously the molecular weight and mass flow rate of the flare gas. The meter is used to conserve energy and reduce product loss by identifying sources of leaks into the flare systems. It also helps improve compliance with pollution-control regulations and reduces energy usage by accurately controlling the amount of steam fed to the flare tip. 90 % lower calibration costs
Permanent monitoring of the sound velocity. Greater reliability through self-diagnosis function 3 D installation length, two HF pulses, Non-volatile volume counter memory. Compatible with turbine meters. The GF90 is a heavy duty industrial gas mass flow meter that offers a wide turndown range of 1000:1, up to 3 different gas calibration groups in operating process temperatures up to 850°F (454°C) and is ideal for a wide range of applications including hazardous environments.

Bi-directional velocity range: 0.1 to 275 ft/s (0.03 to 85 m/s)
Velocity, mass and volumetric flow
Instantaneous gas molecular weight
Measurement independent of composition
No moving parts; nothing to clog or wear out
No regular maintenance required
The GF868 flowmeter operates reliably even under unsteady flow, pulsating pressure, varying composition and temperature, harsh environments and the wide flow ranges typical of flare systems. Flow velocity is measurable from 0.1 to 275 ft/s (0.03 to 85 m/s) bi-directionally in pipe or stack sizes up to 120 in (3 m) in diameter. There are no moving parts or orifices to wear or clog. The GF868 flow measurement is independent of the gas properties, and it does not require regular maintenance.
