ABSTRACT:
A signal generator for an electromagnetic flowmeter provided with a flow tube having an insulated liner through which a fluid to be metered flows to intercept an electromagnetic field established therein to induce a signal depending on flow rate in a pair of electrodes mounted at diametrically-opposed positions on the tube. The field is created by an excitation coil to which is applied an excitation current derived from an external power supply. This signal generator incorporates a current-setting circuit for setting the excitation current to a value establishing a constant relationship between the flow rate of the fluid and the signal yielded by the electrodes.
