摘  要:
A method on sampling and processing the dynamic data from pulsating flow measurement in diesel engines was introduced. Based on a large number of experimental data, the effect of diesel pulsating flow on the measurement error and flow modification coefficient for vortex flowmeter were studied. Using the error method to analyze and process the experimental data, the relationship between flow modification coefficient and pulsating coefficient was obtained, thus a foundation for applying vortex flowmeter in diesel pulsating flow measurement and control was established.
