The DigitalFlow XGF868i from Panametrics is a compact and explosion-proof/flam
e-proof transmitter version of the Panametrics DigitalFlow GF868 flare gas mass flow meter.
The DigitalFlow XGF868 is ideally suited for offshore installations with harsh environments and limited space, but can be applied downstream in refineries and petrochemical plants where Zone 1 is required.
Measures velocity, volumetric and mass flow
Independent of gas composition
Measures instantaneous average molecular weight
High velocity range to 120 m/s (394 ft/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
The DigitalFlow XGF868i flowmeter is a complete ultrasonic flow metering system for:
Flare gas − Track down or prevent losses from leakage with positive material identification − Account for total plant throughput of material − Reduce cost of steam usage with proportional control − Conserve energy by eliminating unnecessary flaring − Comply with government regulations for pollution control
