Introduction to meter scale development and the status quo

Abstract: introduction to meter scale development and the present situation of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. A wide range of flow measurement and instrumentation, classification method is very much also. So far, for industrial use kinds of flow meters more than 60 species. Varieties because so many have yet to find a kind of any fluid, any range, any flow. More flow meter manufacturers choose model price quote you are welcome to inquire, below is the details introduction to meter scale development and the present situation of the article. A wide range of flow measurement and instrumentation, classification method is very much also. So far, for industrial use kinds of flow meters more than 60 species. Varieties because so many have yet to find a kind of any fluid, any range, any flow state and any conditions of use are applicable flow meter. This 60 many kinds of flow meters, each product has its specific applicability, also has its limitation. According to the measured object is divided into a closed tube and two kinds of open channel; According to the purpose and can be divided into the total measurement and flow measurement, the instrument called total table and flow meter, respectively. Total table measure the rate of flow of a period of time through the pipeline, in a short period of time through the total amount divided by the quotient of the time, said flowmeter actually also have accumulated flow devices, usually done using the volume table, table and total also have flow transmission device. Therefore, strictly to flowmeter and total table has no practical significance. According to the principle of measuring points and strong principle principle, thermology, acoustics, electrical principle, optical principle, principle of atomic physics, etc. In this paper, according to the current popular zui, zui broad classification, which is divided into: volumetric flowmeter, differential pressure flowmeter, flow meter, turbine flowmeter, electromagnetic flowmeter, fluid oscillation flowmeter in vortex flowmeter and mass flowmeter and insert the flowmeter to respectively in this paper, the various flowmeter principle, characteristics, application and development situation at home and abroad. (1) differential pressure flowmeter is based on differential pressure type flowmeter installation in pipe flow test to generate differential pressure, fluid known conditions and geometry size of test pieces and pipeline to calculate the flow meter. By a differential pressure type flowmeter device ( Detection) And the second device ( The differential transformation and flow display instrument) Composition. Usually in the form of test pieces classification of differential pressure flowmeter, such as orifice meter, venturi meter, velocity-equalizing tube flowmeter, etc. Secondary device for a variety of mechanical, electronic, mechanical and electrical one-piece differential pressure gauge, differential pressure transmitter and flow display instrument. It has developed into three ( The seriation, generalization and standardization) Degree is high, type specification of confused one kinds of instrument, it can measure flow parameters, and can measure other parameters ( Such as pressure, level, density, etc. ) 。 Differential pressure type flowmeter test according to the principle can be divided into: the throttle device, hydraulic resistance type, centrifugal, dynamic head type, type and fluidic dynamic pressure head gain a few broad categories. Test pieces and according to the degree of standardization is divided into two broad categories: standard and non-standard. The so-called standard test pieces is as long as according to the standard file design, manufacturing, installation and use, without the real flow calibration can determine the flow rate and the estimation error of measurement. Non standard test pieces is less mature degree, not yet on the international standard of test piece. Differential pressure flowmeter is a kind of flow meter, zui widely applied in all kinds of flow meters in its usage occupy the first place. In recent years, due to various kinds of new type flowmeter, its usage percentage gradually decline, but it is still an important class of zui flowmeter. Advantages: ( 1) Application zui orifice plate flowmeter firm structure, stable and reliable performance, long service life; ( 2) Broad application range, so far there is no any kind of flowmeter, which can be compared to; ( 3) Test pieces with transducer and display instrument respectively produced by different manufacturers, is advantageous for the economy of scale production. Disadvantages: ( 1) Measurement accuracy is generally low; ( 2) Narrow range of degrees, generally only 3:1 ~ 4:1; ( 3) Site installation condition demand is high; ( 4) Loss of pressure big, Refers to the orifice, nozzle, etc. ) 。 Application: wide application range, differential pressure type flowmeter in flow measurement in a closed pipe of various objects are used, such as fluid aspects: single phase, miscible, clean, dirt and viscous flow, etc. ; Work status: atmospheric pressure and high pressure, vacuum, normal temperature, high temperature, low temperature, etc. ; Diameter: from a few mm to several m; Flow conditions, subsonic, sonic, pulsating flow and so on. It accounts for about the amount of flowmeter in various industry departments all the dosage of 1/4 ~ 1/3. [2] float float flowmeter of the flow meter, also known as the rotor flow meter, is a kind of variable area flowmeter, under a main scale upward vertical cone tube, the circular cross section of float is under the liquid force of gravity, which can float freely in the cone tube rises and falls. Flow meter application range is second only to differential pressure type flowmeter zui broad class of flowmeter, especially in the small, micro flow has important role. In the mid - 80 - s, Japan, Western Europe, the United States sales amount accounts for 15% ~ 20% of flow meter.
