Hydrocarbon gases are often flared in a high-temperature oxidation process which burns combustible components of waste. Environmental laws and restrictions mandate the precise monitoring of flared gases on oil and gas platforms. A flow meter is required to monitor the waste gases.
Consideration must be given to abruptness of flow change, low pressures, and a wide range of velocities. Thermal dispersion flowmeters are ideal instruments for flare flow measurement due to low flow sensitivity and high turndown.
