Gas Flow Conditioning Devices Used To Pre-condition The Gas Flow Profile Prior To Measurement.
Pipe fittings such as: bends, Tees, reducers, headers, valves, filters, strainers, heat exchangers, etc, affect the velocity profile in the downstream pipe. These profile distortions are known to affect the performance of flow meters. The magnitude of the effect depends upon both the severity of the distortion and the sensitivity of the meter (Ref. 1)
