The development of ultrasonic flow meters 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 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 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. Several points about using ultrasonic flow meters: flow meters have two modes: diagonal and reflection. When the reflection mode cannot be measured, the diagonal mode may be able to measure it, which has led us to continue using the reflection mode. Flow meters have high requirements for pipelines, and a portion of the insulation layer must be scraped off to prevent measurement. When testing the air conditioning water system, we use a knife to cut off a piece of insulation layer to prevent sensors, and then stick the cut insulation layer on after testing. The surface of the pipeline should be as shiny as possible, and if it is too rough, it needs to be sanded with sandpaper. It is difficult to measure when the fluid in the pipeline is not full, so the measurement position should be selected as much as possible in the straight pipe section, away from bends, valves, and other places. The authenticity of flow meter readings depends on signal strength. When the signal is too low, the results are generally unreliable, with a requirement of over 60% or even higher. Due to the possibility of significant fluctuations in readings, our approach is to have the
