What is the principle of integrated standard orifice plate?

The integrated orifice flowmeter is a high range ratio differential pressure flow device composed of a standard orifice plate and a multi parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter). It can measure the flow of gas, steam, liquid, and natural gas, and is widely used in process control and measurement in the fields of petroleum, chemical, metallurgy, power, heating, water supply, etc. Principle of integrated orifice flowmeter: When the fluid filled in the pipeline flows through the throttling device inside the pipeline, the flow beam will form a local contraction at the throttling element of the throttling device, thereby increasing the flow velocity and reducing the static pressure. As a result, a pressure drop, or pressure difference, is generated before and after the throttling element. The larger the flow rate of the medium, the greater the pressure difference generated before and after the throttling element. Therefore, orifice flowmeter can measure the size of fluid flow by measuring the pressure difference. This measurement method is based on the laws of energy conservation and flow continuity. The Paishu Xin intelligent throttling device (flowmeter) is a new generation flowmeter that integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. The instrument adopts advanced microcomputer technology and new micro power consumption technology, with strong functions, compact structure, easy operation, and convenient use. The development of flow measurement can be traced back to ancient hydrauli

c engineering and urban water supply systems. During the time of Caesar in ancient Rome, orifice plates were already used to measure the amount of drinking water consumed by residents. Around 1000 BC, ancient Egypt used the weir method to measure the flow of the Nile River. The famous Dujiangyan Irrigation Project water conservancy project in China uses the water level at Baopingkou to observe the water volume and so on. In the 17th century, Torricelli laid the theoretical foundation for differential flow meters, which was a milestone in flow measurement. Since then, many types of instruments for flow measurement began to take shape in the 19th century, such as weirs, tracer methods, pitot tubes, Venturi pitot tubes, volumetric, turbine, and target flow meters. In the 20th century, the rapid growth in demand for flow measurement in process industries, energy metering, and urban utilities led to the rapid development of instruments. The leapfrog development of microelectronics and computer technology greatly promoted the upgrading of instruments, and new types of flow meters emerged like mushrooms after rain. So far, it is reported that hundreds of flow meters have been put into the market, and many difficult problems in on-site use are expected to be solved. China started developing modern flow measurement technology relatively late, and the flow instruments required in the early days were all imported from abroad. Flow measurement is a science that studies the change of material mass, and the law of mutual change of mass is the basic law of the development of the relationship between things. Therefore, its measurement object is no longer limited to pipeline liquids in the customary sense. Wherever it is necessary to mas
