Description

Product Overview

The PANAMETRICS GF868-1-31-21514-0-0-CC-RPT is the DigitalFlow GF868 flare gas ultrasonic mass flowmeter, designed for flare stack gas measurement in refineries, chemical plants and power generation facilities. It adopts patented Correlation Transit-Time ultrasonic technology to calculate gas mass flow, volumetric flow, velocity and molecular weight, supporting single or dual flare line measurement. This meter solves unstable flare gas measurement issues caused by fluctuating gas composition, low flow and high turbulence, delivering accurate mass balance for environmental reporting and plant flare management. Process automation engineers and reliability teams rely on this spare transmitter for flow metering system maintenance and retrofits. Front panel keypad and LCD support local parameter setup, real-time flow reading and event logging; multiple I/O and communication options transmit measurement data to DCS/SCADA.
