Response of a Coriolis mass flow meter to step changes in flow rate
Henry MP., Clark C., Duta M., Cheesewright R., Tombs M.
Trials have taken place to determine the response of a prototype Coriolis mass flowmeter to step changes in flow rate. The meter typically exhibits a delay of 16 ms, and tracks step changes well. Comparison with previously published results suggests that this performance represents an improvement over several types of current commercial flowmeters. The effect of a correction technique to reduce noise is demonstrated. This is considered valuable, even though it is responsible for 6 ms of the overall delay. A good dynamic response is important in process industry applications with short batch times. © 2003 Elsevier Science Ltd. All rights reserved.
