Patent ID: 7779702

Claim:
A transmitter for a magnetic flowmeter, the transmitter comprising: a current source for energizing the flowmeter, such that the flowmeter generates an induced electromotive force in response to a process flow; memory for storing a non-conforming flow configuration, wherein the non-conforming flow configuration describes an actual flow pipe disturbance in the process flow, and wherein the flow pipe disturbance is located within five pipe diameters upstream or two pipe diameters downstream of the magnetic flowmeter, as installed in the process flow; and a signal processor for determining a flow rate as a function of the induced electromotive force and the non-conforming flow configuration; wherein the signal processor corrects the flow rate based on the flow pipe disturbance such that the magnetic flowmeter achieves a rated accuracy of one fifth percent to less than one half percent in the non-conforming flow configuration.
