Vortex flowmeters have advantages that other flowmeters do not have and have developed rapidly since their introduction. According to statistics, the proportion of vortex flowmeters used in developed countries such as Japan, Europe and America has increased significantly and they have been widely applied in various fields. Judging from the current trend, vortex flowmeters will play a dominant role in future flow meters and are ideal alternatives to orifice plate flowmeters.

Insertable vortex flowmeters are widely used in the measurement of steam, gas and liquid flow due to their advantages such as simple structure, easy installation and low cost. However, in practical applications, its measurement performance is limited by multiple factors. If the selection or use is improper, it may lead to data deviation or even equipment damage. This article will conduct an in-depth analysis of the main limitations of the insertable vortex flowmeter to help users make reasonable selections and optimize their usage.

Vortex flowmeters are widely used in the measurement of steam, gas and liquid flow due to their simple structure, high reliability and wide application range. However, this type of flowmeter is not omnipotent and may experience severe errors or even failure under certain working conditions. This article will reveal five key limitations of vortex flowmeters to help users avoid selection risks.

In modern industrial production, efficient and accurate flow measurement is the key to ensuring process stability and improving energy efficiency management. Vortex flowmeters, with their advantages of simple structure, high reliability and wide application range, have become the “main force” in flow monitoring in industries such as petrochemicals, energy and power, metallurgy and pharmaceuticals, providing solid support for the intelligent upgrade of industry.

Vortex flowmeter is also known as Karman vortex flowmeter. Vortex flowmeter is a kind of separation flowmeter made by using the principle of natural oscillation of fluid. When a fluid flows at a sufficiently large velocity through an object perpendicular to the direction of the fluid, if the object is of appropriate size, it will produce a neatly aligned and reversed vortex train behind the object along two parallel lines.

The working principle of vortex flowmeter is to place a non-streamlined vortex generator in the fluid, so that the fluid is alternately separated on both sides of the generator, releasing two series of regularly staggered vortex flowmeter. In a certain range, the vortex separation frequency is proportional to the flow rate, and the flow rate of the medium can be measured by calculating the vortex separation frequency.

With the continuous production progress of the reform and opening up industry, it has been applied in more and more industries, and the vortex flowmeter is widely used in large, medium and small pipeline water supply and drainage, industrial circulation, and sewage treatment. Oil and chemical reagents as well as compressed air, saturated vapor and superheated vapor, natural gas flow measurement of various media and can be used as a flow transmitter in automated control systems.

Many owners will occasionally encounter that the vortex flowmeter does not have a flow display when using the vortex flowmeter. For this situation, Aister gives the following treatment methods:

Due to the compressibility of the gas, its flow measurement is more complex than that of the liquid, and the output signal of the vortex flowmeter is related to the gas density in addition to the input signal, and the density of the gas is a function of temperature and pressure (referred to as temperature and pressure).

1. Vibration effect

Compressed air is generated by air compressor or high pressure fan. When these devices are in operation, they all have varying degrees of vibration, and sometimes the vibration is relatively strong, and this vibration is transmitted through the connecting pipe. When selecting and determining the position of the vortex flowmeter, this influencing factor should be fully considered. In various detection methods, the anti-vibration performance of the instrument is not the same due to different detection components. For the vortex street of the detection element, the vibration resistance can reach 0.5~1G. When determining the installation position of the vortex flowmeter, it should be as far away from the power equipment such as air compressors and fans as possible.

Vortex flowmeter is a velocity flowmeter, which measures the volume flow rate in the working state. If you choose the table according to the volume flow rate, the mass flow rate provided by the customer should be converted into the volume flow rate under the working state, and then determine the diameter of the selected instrument against the volume flow parameter.

At present, there are many misunderstandings about steam measurement in China, and many users often think that buying a high-price flowmeter can get accurate measurement results. The measurement of steam is different from other fluids such as water, air and other media, and there are many factors affecting its measurement in the actual measurement. Therefore, there is often a phenomenon that the flow meter itself is qualified, but the actual measurement is not “allowed”. So what’s the problem with these factors?

Vortex flowmeter is widely used in various industrial environments, in view of some small problems commonly encountered in the installation of vortex flowmeter, Aister gives the following points, hoping to solve the problems encountered in the installation.
