Flare metering

Flare stacks can be found on almost any oil and gas installation as part of the waste gas system, and as a controlled vent for high volumes of combustible gases during an upset. By its nature, the pressure, volume flow and gas composition in a flare stack can differ significantly over short periods of time. Ultrasonic flow meters are well suited for reliable process control of flares through accurate measurement, ranging from almost zero flow to gas velocities exceeding 120 m/s. By doing so, the optimum ratio of O2 and steam to combustion gas can be ensured and the actual volume of flared gas can be determined.
