A Brief Introduction to Flow Meter

Update:02 Apr 2022

Instruments that measure fluid flow are collectively referred to as flow meters or flow meters. Flowmeter is one of the most important instruments in industrial measurement. With the development of industrial production, the requirements for the accuracy and range of flow measurement are getting higher and higher, and the flow measurement technology is changing with each passing day. In order to adapt to various uses, various types of flowmeters have come out one after another. There are more than 100 flowmeters in use today.

Each product has its specific applicability, as well as its limitations. According to the measurement principles, there are mechanical principles, thermal principles, acoustic principles, electrical principles, optical principles, and atomic physics principles.

Classification according to the structure principle of flowmeter. There are volumetric flowmeters, differential pressure flowmeters, rotameters, turbine flowmeters, electromagnetic flowmeters, vortex flowmeters, mass flowmeters and insertion flowmeters in fluid oscillating flowmeters.

According to the measurement object, there are two categories: closed pipeline and open channel; according to the purpose of measurement, it can be divided into total measurement and flow measurement, and the instruments are called total meter and flow meter respectively. The total meter measures the flow through the pipeline for a period of time, which is expressed by dividing the total amount flowing in a short period of time by the quotient of the time. In fact, the flow meter is usually also equipped with a cumulative flow device, which is used as a total meter. The total meter is also equipped with a flow signalling device. Therefore, it is no longer practical to divide the flow meter and the total meter in a strict sense.
