Abstract: the types of flow meter scale, development and characteristics of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1, the development of the development of flowmeter flow measurement can be traced back to ancient water conservancy projects and urban water supply system. The Roman Caesar orifice measurement has been adopted residents drinking water. Around 1000 BC the ancient Egyptian weir method was used to measure the flow of the Nile. I. More flow meter manufacturers choose model price quote you are welcome to inquire, here are the types of flow meter scale, development and characteristics of the article details. 1, the development of the development of flowmeter flow measurement can be traced back to ancient water conservancy projects and urban water supply system. The Roman Caesar orifice measurement has been adopted residents drinking water. Around 1000 BC the ancient Egyptian weir method was used to measure the flow of the Nile. Our country famous water level observation in dujiangyan water conservancy engineering application BaoPingKou size and so on. In 17th century Joe lay the theoretical foundation of the differential pressure type flowmeter, it marks a significant milestone in the flow measurement. Since then, many types of flow measurement in the 18th and 19th century instrument prototype began to form, such as weir, tracer method, pitot tube, venturi tube, volume, turbine and target flowmeter, etc. Due to the process industry in the 20th century urban public utilities, energy metering, rapidly growing demand for flow measurement, has rapid development, the rapid development of microelectronics technology and computer technology greatly promote upgrading, new type of flowmeter have sprung up. To the market today, boasts hundreds of flowmeter, the use of many thorny problems could be solved. Our country modern flow measurement technology of work late, early the required flow meter are imported from abroad. Flow measurement is the study of material quantity, quality mutual change rule is the basic rule of things development, so the measured object is not limited to the traditional sense of the pipeline fluid, where to master the quantity has the problem of flow measurement. Flow and pressure, temperature and listed as the three major testing parameters. For a certain amount of fluid, just know that the three parameters can be calculated with its energy, in the measure of energy conversion must detect the three parameters. Energy conversion is the foundation of all production processes and scientific experiments, so the same flow rate and pressure, temperature instrument can be zui widespread application. 2, flow meter application fields of the application of flow measurement technology and instrument to roughly the following several areas. Pipe line of type flow meter for measuring fluid flow ( Per unit time through the fluid volume) The instrument. Rotameter, throttle flowmeter, fine seam flowmeter, volumetric flowmeter, electromagnetic flowmeter, ultrasonic flowmeter and weir, etc. 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.
