1. Actual flow rate of vortex flowmeter
The flow formula measured by vortex flowmeter is qv=π D2U/4=π D2mdf/4Sr K=f/qv=[π D2md/4Sr] -1. Under specific flow conditions, a part of the fluid kinetic energy is converted into fluid vibration, and the vibration frequency of the vortex flowmeter is proportional to the flow rate (flow rate). A flowmeter that works based on this principle is called a fluid vibration flowmeter. At present, there are three types of fluid vibration flow meters: vortex street flow meters, vortex precession flow meters, and jet flow meters. Fluid vibration flowmeter has the following characteristics: 1) The output is a pulse frequency, which is proportional to the actual volumetric flow rate of the measured fluid and is not affected by fluid composition, density, pressure, or temperature; 2) The measurement range is wide, and the general range can reach 10:1 or more; 3) The accuracy is above average level; 4) No movable parts, high reliability; 5) The structure is simple and sturdy, easy to install, and has low maintenance costs; 6) Widely applicable, suitable for liquids, gases, and vapors. The working principle is to set up a vortex generator (blocking fluid) in the fluid, and generate regular vortices alternately from both sides of the vortex generator. This type of vortex is called a Karman vortex street, as shown in Figure 1. The vortices are arranged asymmetrically downstream of the vortex generator. Assuming the frequency of vortex occurrence is f, the average velocity of the measured medium flow is U, the width of the vortex generator face is d, and the diameter of the body is D. According to the principle of Karman vortex street, there is a relationship f=SrU1/d=SrU/md. The vortex
