More Information:
The DigitalFlow GF868 ultrasonic flow meter uses the patented Correlation Transit-Time™ technique, digital signal processing, an accurate method of calculating molecular weight.  Add to these features the inherent advantages of ultrasonic flow measurement—reliability with no routine maintenance, high accuracy, fast response, wide rangeability—and the DigitalFlow GF868 flowmeter is the clear choice for flare gas applications. The DigitalFlow GF868 may be used for standard volumetric or hydrocarbon mass flow measurement.  Flow measurement is independent of gas properties, and does not interfere with the flow in any way.  The DigitalFlow GF868 meter achieves a rangeability of 4000 to 1, measuring velocities from 0.1 to 328 ft/s (0.03 to 100 m/s) in standard range, in both directions, while the Extended Range version measures velocities to 394 ft/s (120 m/s) in one direction. In steady or rapidly changing flow, it measures in pipes from 4 in to 120 in (100 mm to 3 m) in diameter.  For base load operation, the volumetric flow in flares is often in the range 0.1 to 1 f/s (0.03 to 0.3 m/s) and the GF868 flare gas flow meter improves the accuracy over that range, but still measures at high velocity during facility relief or upset conditions
