Abstract
An electromagnetic flowmeter includes a flow rate detecting circuit; an exciting circuit for supplying an exciting current to this flow rate detecting circuit; a signal processing section for sampling an output signal from the flow rate detecting circuit and smoothing this sampled output signal; and a signal generating circuit for supplying a sampling signal and an excitation control signal to the exciting circuit and the signal processing section, respectively. This signal generating circuit supplies a sampling signal having the frequency which is apart by a range of 0.5 to 10% from the frequency of the commercial power source to the signal processing section.
