What Flowmeter Should Be Used To Measure The Flow Rate of Compressed Air?

Selection of flow meters for measuring compressed air flow rate

In industrial production processes, compressed air is a commonly used power source, and accurate measurement of its flow rate is crucial for optimizing the production process, improving efficiency, and ensuring the normal operation of equipment. So, how do we choose a suitable flow meter to measure the flow rate of compressed air?

Firstly, we need to understand the characteristics of compressed air. Compressed air has the characteristics of large pressure and temperature fluctuations, as well as high levels of moisture and impurities. Therefore, when choosing a traffic timer, these factors need to be considered.

Differential pressure flowmeter: Based on Bernoulli's theorem, the flow rate is calculated by measuring the pressure difference generated when a fluid flows through a pipeline. This type of flowmeter has a simple structure and high reliability, but it has certain requirements for pipeline straightness and pressure loss. Suitable for measuring medium to large flow rates.

Vortex flowmeter: measures flow rate by using a fluid to form vortices under specific conditions. It has the advantages of wide measurement range, high accuracy, and good stability, but is more sensitive to pipeline vibration and fluid pressure fluctuations. Suitable for measuring small and medium-sized flow.

Thermal flowmeter: calculates the flow rate by measuring the heat loss generated by the fluid flowing through a heat source. This type of flowmeter has advantages such as high measurement accuracy and good stability, but requires regular calibration. Suitable for measuring small and medium flow rates, especially suitable for measuring dry and pure compressed air.

Target flowmeter: calculates flow rate by measuring the pressure distribution of a fluid in a specific area. This flowmeter has a simple structure and high reliability, but is greatly affected by fluid pressure fluctuations. Suitable for measuring medium to large flow rates.

In summary, selecting a suitable flow meter requires considering multiple factors, including the characteristics of compressed air, measurement range, accuracy requirements, etc. In practical applications, suitable flow meters can be selected according to specific situations to ensure measurement accuracy and reliability.
