Quick Summary

A velocity vortex gas meter is a type of flow meter used to measure the rate of gas flow. It operates by directing a portion of the gas flow into an offset chamber where it spins an impeller on a rotor. The rotation of this rotor is then geared to a dial mechanism that records the total volume of gas that has passed through the meter. This method relies on the velocity of the gas to drive the rotor, providing a measurement of gas volume delivered. Velocity gas meters are one of several types, including displacement, head, thermal, acoustic, and tracer meters, each utilizing different principles to measure gas flow.12
