2. Development of differential pressure flowmeter

The development of flow measurement can be traced back to ancient water conservancy 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. 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 in the 19th century have begun to take shape, such as pitot tubes, Venturi 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. Differential pressure flowmeter is a type of flowmeter with a long history of application, rich practical experience, complete standards and specifications, and a complete range of varieties and specifications. Before the 1950s, it may have been the only natural gas flowmeter. It has many shortcomings, such as average measurement accuracy, high requirements for on-site installation conditions, large pressure loss, narr

ow range, etc; In response to the above shortcomings, domestic manufacturers have introduced a series of improvement measures in recent years, such as integrated differential pressure flow meters, fixed value throttling components, replaceable orifice plate throttling devices, and the use of standard nozzles. In addition, since the 1980s, there have been outstanding advances in the two components of differential pressure flow meters: differential pressure transmitters and flow display devices. It is estimated that such flow meters will still occupy an important position in the future. 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 master the quantity change, there are problems with flow measurement. 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, pressure, and temperature instruments are also widely used. The basic requirements for annual inspection and calibration are as follows:
