Abstract
A magnetic flowmeter for measuring a fluid flow includes flow tube assembly receiving the flow having a coil with first and second coil wires for receiving a coil current to produce a magnetic field in the fluid. This generates an EMF in the fluid representative of the flow. An EMF sensor is arranged to sense the EMF and generate an output related to the flow rate. Current supply circuitry provides the coil current to the first and second wires of the coil in response to a command signal. A digital control circuit provides the command signal to the current supply circuitry as a function of a control algorithm. In one aspect, the control algorithm is adapted to changes in electrical parameters of the coil. A method of implementing the magnetic flowmeter is also provided.
