Abstract

In an electromagnetic flowmeter for obtaining a signal corresponding to flow rate of conductive fluid in a magnetic field, a noise detector detects a noise superimposed on the fluid, and a timing signal generator produces timing of generating an exciting current to produce the magnetic field and timing of sampling electrical potential generated in electrodes in the fluid, based on the noise detected by the noise detector.
