The English name of the flowmeter is flowmeter, which is defined by the National Committee for Scientific and Technical Terms as: an instrument that indicates the measured flow rate and (or) the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow of fluid in pipelines or open channels.
Flowmeters are further divided into differential pressure flowmeters, rotameters, throttling flowmeters, slit flowmeters, volumetric flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc. Classified by medium: liquid flowmeter and gas flowmeter.
Metrology is the eyes of industrial production. Flow measurement is one of the components of measurement science and technology, and it is closely related to national economy, national defense construction and scientific research. Doing this work well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today's era of energy crisis and increasing automation of industrial production, flowmeters play an important role in the national economy. position and role are more obvious.
The commonly used unit in engineering is m3/h, which can be divided into instantaneous flow rate (Flow Rate) and cumulative flow rate (Total Flow). Liquid, solid; cumulative flow is the cumulative amount of fluid flowing through the effective section of a closed pipe or open channel within a certain period of time (one day, one week, one month, one year). The cumulative flow can also be obtained by integrating the instantaneous flow with respect to time, so the instantaneous flowmeter and the cumulative flowmeter can also be transformed into each other.
