Description

technical field

[0001] The invention belongs to the field of flow metering systems, in particular to an intelligent magnetic eddy flow detection and control system. Background technique

[0002] The magnetic vortex flowmeter is an instrument that uses the Ferrari excitation principle to measure the vortex shedding frequency of the Karman vortex street and then accurately measure the flow. The magnetic vortex flow detection device adds intelligent control on the basis of pure measurement, especially for real-time monitoring of the working status of the flowmeter itself. The real-time analysis of the confidence of the metering data is an improvement in the application theory of the flowmeter in the technical concept. The Karman vortex flowmeter is designed based on the idea that the stable Karman vortex value and vortex shedding frequency are proportional to the fluid velocity within a certain range of Reynolds number Re. The electromagnetic flowmeter is designed based on the...
