[Chemical Knowledge]：Principle and Application of Target Flowmeter

Read： 515 Time：20months ago Source：Transform the World with Simplicity

In a variety of industrial production and experimental research, the precise control and measurement of fluid flow is very critical. As a common flow measurement instrument, target flowmeter has been widely used in petroleum, chemical, water treatment and other industries. This article will introduce the working principle of the target flowmeter and some of its characteristics in practical application.

target flowmeter is a kind of differential pressure flowmeter. It makes use of Bernoulli's theorem, the principle that in a stable and incompressible fluid, the greater the flow rate, the lower the pressure. By setting a static pressure hole and a total pressure hole in the pipeline, the pressure difference of the fluid can be measured and the flow rate can be calculated. The biggest advantage of

target flowmeter is that it can adapt to the measurement of various media. Because the density and viscosity of the fluid have a great influence on its fluidity, different media have different degrees of influence on the sensor. However, the structural characteristics of the target flowmeter make it more adaptable to the change of the medium, thus ensuring the stability and accuracy of the measurement.

However, target flow meters also have their shortcomings. Its accuracy is relatively low, generally can not reach the accuracy of electromagnetic flowmeter and ultrasonic flowmeter. In addition, the structure of the target flowmeter is relatively complex, which requires a certain maintenance and overhaul cost. Finally, because its measurement principle is limited by Bernoulli's theorem, it is only applicable to incompressible fluids, and the measurement of compressive fluids is not very reliable.

In general, the advantages and disadvantages of target flowmeters in practical applications need to be weighed. Its advantage is to adapt to a variety of media and has a reliable long-term measurement stability, while the disadvantages are low accuracy and high maintenance costs. Therefore, when choosing a flow measurement instrument, it is necessary to consider the production environment and actual needs to make an appropriate choice.

In practical applications, the target flowmeter can be widely used in petroleum, chemical, pharmaceutical, water treatment and other industries, and can also be used in the laboratory for fluid dynamics and physical experiments. With the development of digital technology, target flowmeter is more and more used in industrial automation control system, which provides important support and guarantee for production process and quality control. Therefore, the position and role of the target flowmeter in the industrial field will become more and more important.
