GE DigitalFlow GF868 belongs to the classic 868 series flow measurement product line of GE Inspection Technologies, being a core metering device targeted at complex flare stack gas working conditions in oil refining, chemical industry, natural gas processing plants and chemical park waste gas discharge systemsPanametria.... This flowmeter applies the proprietary Correlation Transit-Time ultrasonic measurement principle, matching high-performance ultrasonic transmitting and receiving sensors to calculate gas flow velocity, combined with built-in gas molecular weight computing module to directly output mass flow data, solving the measurement difficulties of fluctuating flow rate, mixed gas composition and turbulent flow inside flare pipelinesBaker Hugh....

In measurement performance, the equipment features ultra-wide turndown ratio and fast signal response speed, stably captures low-speed leakage gas and instantaneous high-volume venting gas in flare pipelines. Built-in digital signal processing unit filters airflow noise, pipeline vibration interference and medium impurity disturbance effectively, ensuring long-term stable measurement accuracy even under harsh field working conditions. Different from traditional differential pressure flow meters, the ultrasonic measuring mode brings no pipeline pressure drop, will not block the gas channel, and eliminates hidden dangers of flare pipeline backpressure safety accidents.

In hardware configuration, the host is equipped with a high-definition LCD display and a tactile membrane keyboard, supporting on-site parameter setting, real-time flow waveform viewing and historical data query. It is equipped with isolated 4–20mA analog input and output, standard RS232 serial port and optional HART 7 communication module, which can seamlessly access factory DCS, SCADA monitoring systems and environmental protection data acquisition terminals to meet national emission monitoring and data filing regulatory requirementsManualsLib. The metal control cabinet has dust-proof, moisture-proof and anti-electromagnetic interference performance, adapting to outdoor open-air flare platform installation and indoor explosion-proof cabinet layout.

The product supports automatic data logging, which can record continuous flow data for a long time for environmental protection inspection and production process optimization analysis. The non-intrusive measuring sensor structure avoids contact corrosion with corrosive flare waste gas, almost free of daily wearing parts replacement work, greatly reducing regular maintenance workload and equipment shutdown loss for industrial users. It has passed global explosion-proof and industrial safety certifications, and is the mainstream standard metering instrument for flare gas monitoring in global petrochemical enterprises and third-party environmental monitoring institutions.
