GE GF868-1-3EX-20A14-0-0 Torch Gas Ultrasonic Gas Mass Flow Meter Main Unit

Product Description

GE GF868-1-3EX-20A14-0-0 (DigitalFlow GF868, formerly GE Panametrics, now Baker Hughes) is a flare gas ultrasonic mass flowmeter transmitter. Based on transit-time ultrasonic principle, it is designed for flare gas emission measurement. This unit is single-channel with EX certified explosion-proof enclosure. Working with external ultrasonic transducers, it provides non-intrusive measurement with no pressure drop and no moving parts. It calculates gas velocity, volumetric flow and mass flow in real time, with built-in temperature, pressure and supercompressibility compensation for accurate standard volume calculation. Equipped with local LCD display and keypad for configuration, multiple analog outputs and alarm relays plus versatile communication ports. Widely deployed for flare stack emission monitoring in refineries, petrochemical plants and offshore platforms for environmental reporting and flare combustion control. Ordering code GF868-1-3EX-20A14-0-0 defines channel count, explosion-proof housing, I/O and communication options.
