  • Flow disturbance compensation for magnetic flowmeter
    Patent number: 7779702
    Abstract: A transmitter for a magnetic flowmeter comprises a current source, memory and a signal processor. The current source energizes the flowmeter, such that the flowmeter generates an induced electromotive force in response to a process flow. The memory stores a flow configuration that describes a flow pipe disturbance in the process flow. The signal processor determines the flow rate as a function of the induced electromagnetic force, and as a further function of the flow configuration.
