DigitalFlow GF868 Ultrasonic Flare Gas Mass Flow Meter
Measurement of flare gas helps operators comply with environmental regulations, identify points of leakage, and reconcile plant mass balance to achieve optimum operating efficiency. Accurate, worry-free meter performance is a top priority. The GF868 ultrasonic flare meter has amassed the largest global installed base of flare gas flow meters because of its reliable track record.
The Panametrics GF868 flare gas mass flow meter 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 and by accurately controlling the amount of steam fed to the flare tip. It also helps improve compliance with pollution control regulations.
Measurement of flare gas helps operators comply with environmental regulations, identify points of leakage, and reconcile plant mass balance to achieve optimum operating efficiency. So accurate, worry-free meter performance remains a top priority. With its track record of reliability, the GF868 ultrasonic flare meter has amassed the largest global installed base of flare gas flow meters. A meter self-health check feature, called Self-Calibration Check, can give operators confidence in the GF868 by providing reports and proof that the meter is performing as expected.
The meter does the self-heath check, using a proprietary algorithm, at predetermined flowrates and a predetermined hour chosen by operators. The meter will output a PASS if the meter is working correctly or a FAIL if there is any critical failure. In the case of a problem, operators know the status of the meter ahead of time and take actions accordingly.
Features and Benefits
• Operates reliably even under unsteady flow, pulsating pressure, varying
composition and temperature, harsh environments
• Velocity range: 0.1 to 394 ft/sec (0.03 to 120 m/s) or stack sizes up to 120
in (3 m) in diameter
• Bi-directional velocity range: -328 to 328 ft/s (-100 to 100 m/s)
• Velocity, mass and volumetric flow
• Instantaneous gas molecular weight
• PASS/FAIL Self-Calibration Check on meter performance
• Measurement independent of composition
• No moving parts or orifices, nothing to clog or wear out
• No regular maintenance required (flow measurement is independent of
the gas properties)

Best Technology for Flare Gas
Ultrasonic flow measurement, the ideal technology for flare gas applications, is independent of gas properties, and does not interfere with the flow in any way. All-metal ultrasonic transducers installed in the pipe send sound pulses upstream and downstream through the gas.
From the difference in these transit times between the transducers, with and against the flow, the DigitalFlow GF868’s onboard computer uses advanced signal processing and correlation detection to calculate velocity, and volumetric and mass flow rate. Temperature and pressure inputs enable the meter to calculate standard volumetric flow. For maximum accuracy, use the two-channel version and measure along two different paths at the same location. The two-channel meter can also measure the flow in two separate pipes or at two different places on the same pipe.
