An electromagnetic flowmeter assembly comprises excitation coils for generating an excitation field across a flow conduit and electrodes to sense a potential difference from the electromagnetic field generated across the conduit as a result of interaction between the excitation field and fluid flowing along the flow conduit. The signals obtained from the electrodes are processed, together with stored calibration data (51), by processing circuitry to determine flow measurements and means (52) is provided for dynamically updating the calibration data. |
