The existing methods for estimating the error caused by various flow parame
ters for electromagnetic flowmeters are based on nonhomogeneity in the dist
ribution of a weight vector, The author presents a new numerical flow gener
ator, called the moving stream method, that allows for an estimate of the p
rimary error for a flowmeter during the design stage much more precisely th
an classical methods. It considers the contribution to measurement error th
at various flow velocities make within a measurement zone. The simulated fl
ows account for ail hydrologic conditions existing in the field.
