The SHELOK YFV Vortex Flow Meter?is a versatile instrument that finds extensive application in various industries, including petroleum, chemical, metallurgy, thermal, textile, and paper making. It is specifically designed for the measurement and control of superheated steam, saturated steam, compressed air, gases (such as oxygen, chlorine, natural gas, coal gas), as well as liquids like water, gasoline, alcohol, and benzene. In this blog post, we will explore the working principle of the SHELOK YFV Vortex Flow Meter and highlight its key application scenarios.

Working Principle:

The working principle of the SHELOK YFV Vortex Flow Meter?is based on the generation and detection of Karman vortex street. It involves the insertion of a bluff vortex generator, also known as a bluff body, into the fluid flow. As the fluid passes the vortex generator, two regular vortex generators are formed alternately on both sides.

These vortices, collectively known as Karman vortex street, are asymmetrically arranged downstream of the vortex generator. By measuring the separation frequency of these vortices, the instantaneous flow rate can be calculated. The relationship between the frequency of vortex occurrence (f), the average velocity of the fluid (V), the width of the vortex generating body (d), and the diameter of the surface body (D) can be described by the formula:

f = St × V / d

In this equation, f represents the frequency of Karman vortex generated on one side of the generator, St refers to the Strohal number (a dimensionless parameter), V denotes the average velocity of the fluid, and d represents the width of the vortex generator.
