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 measurementreliability with no routine
maintenance, high accuracy, fast response, wide rangeabilityand 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

Device Support File Usage
FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
