Abstract: The present invention relates to a method of configuring an electromagnetic flowmeter and an electromagnetic flowmeter thereof. The method comprises: obtaining a first correlation factor between flow rate of fluid and potential for a calibrated condition of the electromagnetic flowmeter using a model; obtaining a second correlation factor between flow rate of fluid and potential for conditions of a site in which the electromagnetic flowmeter is installed using the model; comparing the first correlation factor and the second correlation factor to determine a difference in value and adopting the value of the second correlation factor for configuring the electromagnetic flowmeter if the difference in value exceeds a pre-set threshold.

Abstract: An electromagnetic flowmeter for monitoring a flow rate of a fluid includes a conduit and an electromagnetic assembly coupled to the conduit to generate a magnetic field inside the conduit. A ring assembly modifies a velocity profile of fluid arranged on an inner liner wall of the conduit. A position of the ring assembly is adjustable along the inner liner wall to varyingly reform the velocity profile of the fluid. A pair of electrodes mounted to the conduit detects induced voltage generated within the reformed fluid due to the magnetic field. The flow rate of the fluid is determined based on the induced voltage.

Abstract: The present invention provides for a method for operating an electromagnetic flowmeter capable of being mounted on to a surface of a flow pipe for measuring a flow of fluid flowing in the flow pipe. The method comprising: exciting the coil to have electromagnetic interaction with the fluid in the flow pipe resulting in leakage current; providing a current to compensate for the resulting leakage current in the flow pipe by applying a potential difference to electrodes that are attached to a housing of the electromagnetic flowmeter and in contact with the flow pipe; detecting a condition wherein the resulting current flowing is within a threshold range; and determining a measure of flow in the flow pipe based on a value of the applied potential difference.

Abstract: An electromagnetic flowmeter and method for measuring a flow of a fluid through a conduit includes utilizing at least two coils, at least two electrodes, and a control circuitry. The at least two coils are electrically excited to generate a magnetic field within a flowmeter fluid space. First and second coils are placed around first and second central axes of the conduit. The at least two electrodes are arranged diametrically opposite to each other to detect an induced voltage in the flowmeter fluid space in response to the generated magnetic field. The control circuitry for measuring the induced voltage on each of the at least two electrodes provides a measure of flow of the fluid.
