Abstract

The existing methods for estimating the error caused by various flow parameters for electromagnetic flowmeters are based on nonhomogeneity in the distribution of a weight vector. The author presents a new numerical flow generator, called the moving stream method, that allows for an estimate of the primary error for a flowmeter during the design stage much more precisely than classical methods. It considers the contribution to measurement error that various flow velocities make within a measurement zone. The simulated flows account for all hydrologic conditions existing in the field
