Extract

At the present time, the only established method of metering a pulsating fluid flow involves the installation of damping devices in the system between the source of pulsation and the flow meter to ensure that the flow through the meter is essentially steady. Such devices may comprise a combination of frictional and volumetric damping and the method by which the required degree of damping is determined makes use of the Hodgson criterion. In many systems, it is undesirable (or, at least, inconvenient) to have to incorporate this damping and, therefore, the more direct approach, involving the metering of flow which is actually pulsating, is of considerable practical interest.

In the present note, the various factors affecting the metering errors in pulsating flow are discussed in relation to the results of an experimental investigation into the pulsating flow of air through a number of standard orifice configurations.
