Relation between the velocity profile and the sensitivity of electromagnetic flowmeters j.A.Shercliff
Answers
Answer:
Electromagnetic flowmeters are commonly known to be quite insensitive to velocity profile effects. However, the test results show that even the best meters are sensitive to disturbances in the flow. In practice it is very difficult to test meters in all possible pipe configurations. Numerical methods are therefore suggested as a solution to this problem. In any case, accurate mathematical modelling of the flow and the meters is needed. The magnetic field of an electromagnetic flowmeter has been measured and the model for the meter has been computed. Measured and computed values of the velocity profile of water flow have been used to estimate the error.
