GF868 Ultrasonic Flare Gas Flowmeter
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) standard bi-directionally in pipe or stack sizes up to 120 in (3 m) in diameter. Extended performance range configuration is available to 395 ft/s (120 m/s) velocity. 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.
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.
