Abstract: Analyses of unsteady flow in pipe systems are normally applied in case periodic pulsations are to be expected as a result of well known sources like reciprocating compressors or other positive displacement machinery. The API 618 Standard for reciprocating compressors recommends such a pulsation and mechanical response analysis to prevent unacceptable vibration levels and cyclic stresses in the piping and connected instrumentation. However the impact of pulsating flow on flowmeter accuracy is not considered and criteria for allowable pulsations at flowmeters in relation to metering errors are not specified in the present edition of the standard.
