DigitalFlow XGF868i Ultrasonic Flare Gas Mass Flow Transmitter


The Panametrics DigitalFlow XGF868i is a low-cost, compact, and explosion-proof/flame-proof transmitter version of the Panametrics DigitalFlow GF868 flare gas mass flow meter. The XGF868i not only improves the efficiency of petrochemical plants, refineries and offshore platforms, but is used to conserve energy and reduce product loss by identifying sources of leaks into flare systems. It also improves compliance with pollution control regulations and reduces energy usage by accurately controlling the amount of steam fed to the flare tip.

Features and Benefits


• CSA, ATEX, and IECEx certifications

• Operates reliably even under unsteady flow, pulsating pressure, varying

  composition and temperature, harsh environments and the wide flow

  ranges typical of flare systems

• Measures velocity, volumetric and mass flow

• Delivers accurate flow rate, independent of gas composition

• Measures instantaneous average molecular weight

• Flow velocity is measurable from 0.1 to 394 ft/s (0.03 to 120 m/s) in

  pipes 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)

• Accurate low flow rate measurement, 4000-to-1 turndown ratio

• One- or two-path configurations

• Allows cross flow immunity in large pipes

• Minimal maintenance due to no moving parts, no holes or tubes, and

  tolerance to dirty or wet conditions

• No pressure drop

• Field-proven installation techniques

• Easy serviceability

Flare Gas Flow Meter


The DigitalFlow XGF868i ultrasonic flow meter uses the patented Correlation Transit-Time™ technique, digital signal processing, and 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 XGF868i flow meter is the clear choice for flare gas applications.


Compact Housing


All of the DigitalFlow XGF868i's electronic components are housed in a compact, low cost, explosionprof/flameproof transmitter package that can be installed close to the flow measurement point. This greatly simplifies wiring of the flowmeter.


Simple Installation


The flow meter system consists of a pair of transducers and insertion mechanism for each channel, and an XGF868i. The transducers can be installed as part of a flowcell, or directly into the pipe with a hot or cold tapping procedure. The DigitalFlow XGF868i meter can be located up to 1,000 ft (300 m) from the transducers.
