Flare metering

Flare stacks can be found in every refinery as an integral part of the safety and waste gas system as they allow controlled venting for large volumes of combustible components during upset conditions. By their nature, pressure, volume flow, and composition of flare gases can change considerably in short periods of time. Modern ultrasonic gas flow meters are able to tackle this challenge with a broad dynamic range covering low-flow conditions as well as gas velocities beyond 120 m/s. Also, these flow meters can measure steam and natural gas.
