Vortex flowmeter based on Kamen vortex theory, the use of fluid through the non-streamlined objects generated by the vortex phenomenon to measure the flow.
Vortex flowmeter, as a precision measuring instrument widely used in industrial production, environmental monitoring and energy management, the core principle behind it is the famous Karman vortex theory. Below, we will explain this theory and its application in vortex flow meters in detail in easy-to-understand language.
First, let’s start with what a vortex flowmeter is. A vortex flowmeter is an instrument that uses the vortex phenomenon generated when fluid passes through a non-streamlined object to measure flow. Its core component is usually a columnar or streamlined object called a "vortex generator".
So, what is Karman vortex street theory? This theory was proposed by Hungarian-American scientist Theodore von Kármán in 1911. When studying the flow of fluid around obstacles such as cylinders, he discovered that when the flow velocity reaches a certain value, two rows of vortices will periodically alternate behind the obstacle. This regular vortex row is called a "vortex street." . The frequency of this vortex street has a certain relationship with the speed of the fluid and the geometry and size of the obstacles.
In the vortex flowmeter, this "vortex generator" acts as an obstacle in the above theory. When a fluid (such as water, gas or steam) flows through a vortex generator, a series of vortices are formed according to Karman's vortex street theory. The frequency of vortex shedding is directly related to the fluid velocity, and this frequency can be detected by a sensor and converted into an electrical signal to calculate the volumetric flow rate of the fluid.
In summary, the vortex flowmeter cleverly uses the Karman vortex theory to indirectly reflect the flow rate of the fluid by measuring the frequency of vortex shedding, thereby achieving accurate measurement of flow. This measurement method has the characteristics of good stability, high accuracy, and wide application range. It is an indispensable flow measurement tool in modern industrial production and scientific research activities.
The thermal mass flow meter is designed based on the principle of thermal diffusion. The instrument uses the constant temperature difference method to accurately measure the gas. It has the advantages of small size, high degree of digitization, convenient installation and accurate measurement. Reduce your energy costs and increase your sustainability. Monitor your consumption and analyze your leakage flows with just one measuring device.
Mass Flow Meter is a new type of advanced flow measurement instrument and has been rapidly developed in the world. It has been widely used for process detection and custody transfer measurement in many industries such as petroleum, petrochemical, chemical, pharmacy, marine, pharmaceutical, municipal, paper, food and energy and so on. It has been highly valued by the flow research community and welcomed by users at home and abroad.
