Abstract
An improved method and apparatus for measuring gas flow from producing wells using a dynamic pressure transducer to monitor the dynamic pressure in the gas flow. The measured dynamic pressure signal is filtered to remove high frequency components and the resulting signal is converted to a RMS signal. The RMS signal is proportional to the density of the fluid and the square of the fluid velocity. Fluid flow can be calculated by measuring the temperature and static pressure of the fluid and combining these measurements with the measured dynamic pressure.
