ABSTRACT:
An electromagnetic flowmeter and a method for measurement of the rate of flow of a fluid under unsteady conditions are described. It uses fluid steady-state flowmeter technology and a new algorithm to measure transient rate of flow of a fluid such as water. The algorithm teaches (a) measuring the e.m.f. generated due to the rate of flow of the fluid under test moving through a tube placed in an area with uniform magnetic flux, and (b) comparing it to a simultaneously generated reference signal which is measure of the magnetic flux density generated when an electromagnetic flowmeter is energized due to the fluid flow rate at the instant of taking the flow rate data of the fluid.
