Abstract

See full text

A method of damping pulsations produced by an engine or other driver, so that gas flow can more accurately be measured by a gas flow meter. A damping device is placed between the driver and the flow meter, and has an enclosed volume, an input tube, and an output tube. Particular dimensions of the damping device, namely the volume of the chamber and the diameter and length of the input tube, are calculated to result in a desired damping efficiency.
