Problems solved by technology

[0003] Existing vortex flowmeters are prone to affect the accuracy of measurement signals when encountering external vibrations during flow measurement
Although various existing technologies have adopted many compensation methods to reduce noise effects, none of these compensation methods are sufficient to reduce the effects of noise, especially difficult to compensate for flow disturbances

Abstract

The invention provides an embedded flow meter. The embedded flow meter comprises a telescopic rod and an embedded flow meter element; the telescopic rod is connected with the embedded flow meter element, so that the embedded flow meter element is arranged in the guide pipe; the embedded flow meter element is arranged in the center of the guide pipe; the flow meter element comprises a main body, the main body comprises a flow opening, and the main body is arranged between an opening inlet and an opening outlet of the flow opening; the opening axis of the flow opening is perpendicular to the axis of the main body; the flow opening comprises a top wall, a bottom wall, a first side wall and a second side wall, and the length of the top wall exceeds that of the bottom wall; the vortex generating element is also included and arranged in the flow opening and comprises a panel, an upper surface and a lower surface, wherein the panel extends in the direction perpendicular to the opening direction of the flow opening; the embedded flow meter has the advantages that eddy current sensing caused by flowing noise is reduced, and then the situation that the precision of the flow meter is affectedis reduced.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, in particular to an embedded flowmeter. Background technique [0002] Vortex flowmeters are used in the field of industrial process measurement and control for measuring the flow of fluids. A vortex flowmeter is typically inserted into a flow tube carrying the fluid to be measured. Industrial applications include petroleum, chemical, pulp and paper, mining and materials, oil and gas. The working principle of the vortex flow meter is based on the phenomenon of vortex shedding known as von Karman effect. As the fluid passes through the bluff body, the fluid separates and creates vortices that alternately shed along and behind each side of the bluff body. These vortices cause areas of fluctuating pressure that are detected by sensors installed in or downstream of the bluff body. [0003] Existing vortex flowmeters easily affect the accuracy of measurement signals when they encount...
