Abstract:
1. An electromagnetic flow meter for measuring the flow rate of a conductive fluid in a conduit, the electromagnetic flow meter comprising: an electromagnetic transducer designed and configured to produce a magnetic field that extends into the conductive fluid within the conduit so as to induce an electrical potential within the conductive fluid; a driver circuit designed and configured to drive said electromagnetic transducer with an electrical current so as to produce the magnetic field, said driver circuit including a current transducer, said current transducer designed and configured to produce a current signal representative of the electric current; at least two electrodes designed and configured to transmit an electric potential signal representative of the electric potential of the conductive fluid; a signal conditioning unit in electrical communication with said at least two electrodes, said signal conditioning unit generating a conditioned signal from said electric potential signal; and a signal processing unit electronically coupled to said signal conditioning unit and said driver circuit, said signal processing unit designed and configured to determine a flow rate from said conditioned signal and said current signal.
