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 has a wide range of applications, all single-phase flows can be measured, and some mixed phase flows can also be applied. The standard throttling device does not require real flow calibration and can be put into use. The installation of integrated orifice plates is simpler, without the need for pressure pipes, and can be directly connected to differential pressure transmitters and pressure transmitters. Adopting imported monocrystalline silicon intelligent differential pressure sensor. The 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 micro power consumption new technology, with strong functions, compact structure, easy operation, and convenient use. Orifice plate is a differential pressure generating device for measuring flow rate, which can be used in conjunction with various differential pressure gauges or transmitters to measure the flow rate of various fluids in pipelines. The throttling device includes annular orifice plate, nozzle, etc. The throttling device is used in conjunction with differential pressure transmitters to measure the flow rates of liquids, vapors, and gases. It is widely used in industries such as petroleum, chemical, metallurgy, wind power, and light industry. In the production of the power industry, the measurement and regulation of the flow rate of liquids, gases, steam and other media play an important role. The accuracy of flow measurement not only has great economic significance for ensuring the operation of power plants under parameters, but also has become an important link in ensuring the safe operation of power plants with the development of high temperature, high pressure, and large capacity units. In the steel industry production, the flow measurement of circulating water and oxygen (or air) during the steelmaking process is one of the important parameters to ensure product quality. In industries such as light industry, food, and textiles, flow measurement is also indispensable.

2. 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.
