Turbine flowmeter and volumetric flowmeter, Coriolis mass flowmeter is called products in three categories of repeatability, precision in the best, as one of the ten types of flow meter, its product has been developed for the scale of many varieties and series of batch production. Turbine flowmeters are widely used in the following areas: petroleum, organic liquids, inorganic liquids, liquefied petroleum gas, natural gas and cryogenic fluids. In Europe and the United States, turbine flowmeter is natural orifice flowmeter measurement instrument after the dosage, only in Holland natural gas pipeline on the use of more than 2 thousand and 600 sets of various sizes, pressure from the gas turbine flowmeter 0.86.5MPa, they have become excellent natural gas measurement instrument. At present, the turbine flowmeter has the following characteristics, high precision, in all flowmeters, is the most accurate flowmeter, good repeatability, no zero drift, good anti-interference ability, wide range, compact structure. The physical property of the fluid has a great influence on the flow characteristics for a long time.

With the development of energy sources at home and abroad, especially the application of natural gas, the rapid development of gas turbine flowmeter is promoted. Currently on the market can be divided into flowmeter, volumetric flowmeter, differential pressure flowmeter, float flowmeter, turbine flowmeter, electromagnetic flowmeter, the fluid oscillation in the flowmeter vortex flowmeter, mass flowmeter and insert flowmeter. The turbine meter, is the main type of velocity type flowmeter in the rotor, it adopts multi blade (turbine) the average velocity of fluid feeling but, from the derived flow or amount of instrument.

Jiangsu gold Meter Co., Ltd. to explain flow measurement is one of the components of the measurement of science and technology, it has a close relationship with the national economy. Especially in today's energy crisis, industrial production automation is becoming more and more high, the phenomenon of serious waste of energy use, the flow meter has become more and more important, and more and more people pay attention to it. As the most common turbine flowmeter flowmeter, has the characteristics of high precision, good repeatability, and is widely used in industrial and agricultural production, transportation, national defense, scientific research, foreign trade, and people in every corner of life. With the rapid development of computer technology, the research and development of high speed gas turbine flowmeter based on single chip computer is more and more important.

The turbine flowmeter is a kind of velocity meter, it has the advantages of high accuracy, good repeatability, simple structure, fewer moving parts, high pressure resistance, wide measurement range, small volume, light weight, small pressure loss, easy maintenance etc.. Measurement of volume flow and total volume of low viscosity gas in closed conduits. It is widely used in petroleum, chemical industry, metallurgy, city gas pipeline network and other industries. The design of high speed turbine flowmeter based on MCU, save resources, improve system performance, can eliminate the system error, the more quickly and accurately calculate the fluid density and flow value, ensure the system accuracy and real-time, has good application value and price.
