Development: The development of flow measurement can be traced back to the ancient water conservancy projects and urban water supply systems. In the ancient Roman Caesar era, hole plates were used to measure the drinking water volume of residents. Ancient Egypt measured the flow of the Nile around 1000 BC. China's famous Dujiangyan water conservancy project used Aquarius water level to observe the water size and so on. In the 17th century, Torridemolition laid the theoretical foundation of differential pressure flow meter, which was a milestone in flow measurement. Since then, the prototype of many types of instruments of flow measurement in the 18th and 19th centuries began to take shape, such as weir, tracing method, skin trusteeship, venturi tube, volume, turbine and target flow meter. In the 20th century, due to the rapid increase of the demand for flow measurement in process industry, energy measurement and urban public utilities, the rapid development of instruments promoted. The leap development of microelectronics technology and computer technology greatly promoted the upgrading of instruments, and new flow meters mushroomed like bamboo shoots after a spring rain. So far, it is said that hundreds of flow meters have been invested in the market, and many difficult problems in site use are expected to be solved.
Flow measurement is a science to study the change of material quantity, and the law of mass mutual variation is the basic law of the development of things, so the measurement object is not limited to the pipeline liquid in the traditional sense, where the quantity change needs to be mastered, there is the problem of flow measurement. Flow rate, pressure and temperature are also listed as the three major detection parameters. For a certain fluid, the three parameters can be calculated as long as the three parameters are know, which must be detected in the measurement of the energy conversion. Energy conversion is the basis of all production processes and scientific experiments, so flow and pressure, temperature instruments are as the most widely used.
ROTA METER is a variable area flow meter based on float position measurement. Rotor flow meter is easy for installation and maintenance, and can be widely used in the flow measurement and process control of complex, harsh environment and various media conditions.
Applications: Glass rotor FLOW METER is widely used in chemical industry, petroleum, light industry, medicine, environmental protection, food and measurement testing, scientific research and other departments, to measure the flow rate of single-phase non-pulsatiating fluid (liquid or gas). Glass GAS FLOW METER has strong corrosion resistance, can detect acid (except hydrofluoric acid), alkali, oxidant and other corrosive gas or liquid flow, and flow meter is suitable for chemical, pharmaceutical, paper, sewage treatment and other industries.
