Abstract: Puisalion is still a major problem in measurement of flow and therefore methods of coping with it are worthy of review at this time. It is not my purpose to tell you of any revolutionary technique or to expose any new theory, but rather to lay out what I think is a reasonable approach in eliminating pulsation error in measurement by use of pulsation dampeners. The term pulsation in this paper is meant to be the variation in pressure. Pulsation usually occurs at a uniform rate or so many cycles per second. The amount of pulsation is usually referred to as amplitude or peak-to-peak amplitude (Figure 1). In practice, a pulsating wave is usually composed of several different frequencies. These different frequency components have been summed together to form a more complicated wave as in Figures 2 and 3. Figure 3 is an actual recording of a pulsating wave measured in a pipeline. The frequency analysis is listed below it.
