Looking to Lessen Fluctuating Flow Problems in Measurement
By Chris Mills, Engineer, TÜV SÜD National Engineering Laboratory, United Kingdom Good measurement practices suggest flow measurements should occur without instabilities or pulsations in the flow. Even minor inaccuracies in the measurement of high-value products can lead to significant financial exposure over extended periods of time. Given the high product value and throughput of most hydrocarbon production processes, a great deal of importance is placed on the accuracy of these measurements. For oil flow measurement, turbine, Coriolis and ultrasonic flow meters are the most commonly used flow meters. However, as oil production declines, these measurement technologies are experiencing su
