Nowadays, hundreds of flow meters have been applied into the market. Many intractable problems in the field use are expected to be solved.
Flow measurement is a study of changes in the quantity of matter. The law of mutual change of quality and quantity is the basic law of the development of relation between things.Therefore, the measurement object of the flowmeter is not limited to the pipe liquid in the traditional sense. Where there is a need to master quantitative variation, there is the problem of flow measurement.
Flow rate, pressure and temperature are listed as the three major detection parameters. These three parameters must be tested in the measurement of energy conversion. Energy conversion is the basis of all production processes and scientific experiments. Therefore, the flow meter has been widely used as same as the pressure and temperature meters.
