摘要:
The dynamic performance of electromagnetic flowmeters is limited by the fundamental frequency of the magnetic field which is used to excite the flowmeter. The reasons why these fields cannot be increased in frequency without causing significant problems are identified. Two potential solutions to overcome the limited dynamic performance whilst at the same time achieving good long term stability are identified.
