GE GF868-1-3EX-20A-14-0-0 Torch Gas Ultrasonic Mass Flowmeter

roduct Description

GE DigitalFlow GF868-1-3EX-20A-14-0-0 (Panametrics) is a flare gas ultrasonic mass flowmeter, adopting patented Correlation Transit-Time™ ultrasonic technology. It can real-time calculate gas velocity, volumetric flow, mass flow and average molecular weight of gas. Model code definition: single channel, EX intrinsically safe explosion-proof version, matched with 20A transducer, with corresponding I/O and communication configuration. It has no moving parts or orifice, not easy to clog or wear. Suitable for hydrocarbon flare gas with dynamically changing composition, supporting wide turndown measurement. The transmitter integrates totalizer and can supply power to temperature & pressure transmitters. Widely used for flare emission monitoring in refinery and petrochemical industry. Originally GE Panametrics product line, now belongs to Baker Hughes, some variants are discontinued.
