Description

Technical Field

[0001] The utility model relates to the technical field of vortex flowmeters, in particular to a vortex flowmeter with automatic error correction based on the influence of Reynolds number. Background Art

[0002] The vortex flowmeter is a flow measurement instrument based on the Karman vortex principle. It is mainly used to measure the volume flow rate, standard volume flow rate or mass flow rate of gas, steam or liquid. The working principle of the vortex flowmeter is to use the fluid oscillation principle to measure the flow rate. A triangular prism-shaped vortex generator is set in the fluid. When the fluid passes through the pipeline, two rows of vortices proportional to the flow velocity are generated alternately up and down behind the vortex generator. This vortex is called a Karman vortex. The release frequency of the vortex is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator. By measuring the vortex frequency, the average velocity of the fluid flowing through the vortex generator can be calculated, and then the flow rate can be calculated.

[0003] Existing vortex flowmeters, such as the prior art with application number CN202321269231.3, include a vortex flowmeter body mechanism, a vortex flowmeter body, a workbench mechanism, a workbench, a mounting bracket, a connecting rod hole, a connecting rod and a universal wheel, etc. By providing a lift slot, a lift and a placement plate, when the vortex flowmeter body is placed on the workbench and the position is low, it is inconvenient for the staff to install it. The vortex flowmeter body can be lifted by the placement plate through the lift, and the height of the vortex flowmeter body can be flexibly adjusted.
