Flowmeter      

Definition: A meter that indicates the measured flow and / or the total amount of fluid in a selected time interval.
Applied disciplines: mechanical engineering (first-level discipline); industrial automation instruments and systems (second-level discipline); flow measurement instruments-flow measurement instrument name (third-level discipline)

An instrument used to measure the fluid flow (volume of fluid passing in a unit time) in a pipeline. Jinhu Dongxiang Instrument Co., Ltd. has carried out some simple analysis on the classification of flowmeters through many years of experience in the production and sales of flowmeters :

There are many types of flow measurement methods and instruments, and many classification methods. So far, there are as many as 60 types of flow meters available for industrial use. The reason why there are so many types is that no flow meter has been found that is suitable for any fluid, any range , any flow state, and any use conditions.

These more than 60 kinds of flow meters, each product has its specific applicability, but also has its limitations. According to the measurement object, there are two categories: closed pipes and open channels . According to the purpose of measurement, it can be divided into total measurement and flow measurement. The instruments are called total meters and flow meters .

The total meter measures the flow through the pipeline over a period of time. It is expressed by the quotient of the total flow flowing in a short time divided by the time. In fact, the flow meter usually also has a cumulative flow device for the total meter The total meter is also equipped with a flow signalling device. Therefore, it is no longer practical to separate flow meters and total meters in a strict sense.

According to the measurement principles, there are mechanical principles, thermal principles, acoustic principles, electrical principles, optical principles, and atomic physics principles.

According to the most popular and widely used classification method at present, it is divided into: volumetric flowmeter , differential pressure flowmeter , float flowmeter , turbine flowmeter , electromagnetic flowmeter , vortex flowmeter in fluid oscillation flowmeter , quality Flowmeters , plug-in flowmeters , and probe-type flowmeters are used to explain the principles, characteristics, application overview, and domestic and foreign developments of various flowmeters.

According to the principle of flowmeter mechanism, there are volume flowmeter , impeller flowmeter , differential pressure flowmeter, variable area flowmeter , momentum flowmeter, impulse flowmeter , electromagnetic flowmeter, ultrasonic flowmeter and mass flowmeter. , Fluid oscillating flowmeter , rotor flowmeter .
