Abstract
An electromagnetic flow meter includes a fluid-carrying conduit. A signal detecting element detects an electromotive force induced in the fluid in the conduit to produce a first detecting signal. A conduit voltage detecting element detects a voltage of the conduit to produce a second detecting signal. An electrical energy applying device is responsive to the first and second detecting signals for applying a selected amount of voltage to the conduit so that the voltage of the first detecting signal and the detected voltage of the conduit become equal to each other, whereby a profile of the voltage of the conduit is substantially similar to a profile of the electromotive force at least at a position of the signal detecting element.
