1. Development Overview of Integrated Orifice Flow Meter The development of flow measurement can be traced back to ancient hydraulic 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 tubes, volumetric, turbine, and target flow meters. In the 20th century, the rapid growth in demand for flow measurement in the process industry, energy metering, and urban public 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, and there are problems with flow measurement wherever it is necessary to master the quantity change. Flow rate, pressure, and temperature are listed as the three major detection parameters. For a certain fluid, as long as these three parameters are known, its energy can be calculated, and these three parameters must be detected in the measurement of energy conversion. Energy conversion is the foundation of all production processes and scientific experiments, therefore, flow cytometry leak gauges, pressure and temperature instruments are also widely used.

2. What is the true meaning of integrated orifice plates? The orifice plate has an international standard (ISO 5167). By measuring the pressure difference at both ends of the orifice plate, a flow rate value with certain accuracy can be calculated according to this standard. The pressure measurement methods for orifice plates are specified in international standards as three types: radial pressure measurement, flange pressure measurement, and corner pressure measurement (with pressure measurement holes adjacent to the orifice plate). When measuring liquids or gases containing a small amount of solid or liquid, in order to facilitate the passage of a small amount of solid or liquid, the opening of the orifice plate can be made into a fan-shaped shape or made eccentric to the axis of the pipeline Features: The structure of the throttling device is easy to replicate, simple, sturdy, and has stable and reliable performance, making Yinkai have a long service life and a low price. The calculation of orifice plate adopts international standards and processing: it h
