flow meter introduction

- Jan 12, 2018 -

flowmeter, the National Science and Technology Terminology validation committee to define it as: Indicate the measured flow and (or) the total amount of fluid in the selected time interval meter. In simple terms it is a gauge used to measure the flow of fluid in a pipe or open channel.

Flowmeter is divided into a differential pressure flowmeter, rotor flowmeter, throttling flowmeter, slit flowmeter, volume flowmeter, electromagnetic flowmeter, ultrasonic flowmeter. According to the media classification: liquid flow meter and gas flow meter.


Overview editor

Metering is the eyes of industrial production. Flow measurement is one of the components of measurement science and technology. It is closely related to the national economy, national defense construction and scientific research. To do a good job of this work will play an important role in guaranteeing product quality, improving production efficiency and promoting the development of science and technology. Especially in the current era where the energy crisis and industrial automation are getting more and more advanced, the flowmeter in the national economy The status and role of the more obvious.


Commonly used unit of engineering m3 / h, it can be divided into the instantaneous flow rate (Flow Rate) and the total flow (Total Flow), instantaneous flow rate per unit time over the closed pipe or open channel effective cross-section of the amount of material flow through the gas, Liquid, solid; The cumulative flow rate is the cumulative amount of fluid flowing through the closed pipe or open channel effective section over a period of time (one day, one week, January, one year). The cumulative flow can also be obtained by integrating the instantaneous flow with time, so the instantaneous flowmeter and the cumulative flowmeter can also be transformed into each other. 

Development trend editor


At industrial sites, meters that measure fluid flow are collectively referred to as flow meters or flow meters. It is one of the most important instruments in industrial measurement. With the development of industry, the accuracy and range of flow measurement are increasingly demanding. In order to meet a variety of uses, various types of flowmeters have come into being one after another and are widely used in petroleum and natural gas, petrochemical industry, water treatment, food and beverage, Pharmaceutical, energy, metallurgy, pulp and paper and building materials industries.

Frost & Sullivan Consulting uses a 360-degree full-view study model to focus on the global, integrated application industry, technology and technology development, economy, competitive environment and industry users and many other modules to conduct a comprehensive study on the flowmeter market. In this paper, the target flowmeter, volumetric flowmeter, turbine flowmeter, differential pressure flowmeter, variable area flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, vortex flowmeter Coriolis mass flow meter and plug-in thermal mass flow meter as the research object, the market analysis.

In 2008, the global market of flow meters reached 2.83 billion USD, an increase of 3.9% over 2007.
