GE XGF868i-2-1-OI-H-3-4-RPT-0 Ultrasonic Torch Gas Mass Flow Transmitter

Product Description

Model: XGF868i-2-1-OI-H-3-4-RPT-0, Baker Hughes (Panametrics) DigitalFlow XGF868i explosion-proof flare gas ultrasonic mass flow transmitter. This ordering code is 2-path configuration. Based on ultrasonic time-of-flight principle, it has no moving internal parts. It directly measures gas velocity, volumetric flow, mass flow and real-time average molecular weight, independent of gas composition variation. This unit integrates RPT pressure & temperature compensation module with OI optical interface. Equipped with Ex flameproof enclosure, designed for harsh Zone1 hazardous area, widely used for flare gas metering in refineries and offshore platforms.
