ABSTRACT:
In an electromagnetic flowmeter one of two electrodes mounted on a measuring pipe is impressed with an electrical pulse synchronous with the switching of an excitation currrent, thereby detecting the voltage drop across the electrical resistance of a fluid, such that both the conductivity and the flow rate of the fluid are measureable at the same time.
