At present, the technical development trend of total flow measurement in my country is getting faster, and various excellent flow meters have been used in industrial production reasonably. However, the performance indicators of different flow meters have certain differences, and the application fields are also different. They are not the same, but ultrasonic flow meters can be widely used in various places, and are suitable for many fields such as agriculture and animal husbandry, wastewater treatment.The pipe-segment or clamp on ultrasonic flow meter should use the "rate difference method" as the basic principle to measure the total flow of liquid in the round steel tube.It uses excellent multi-single pulse technology, data signal intelligent solution technology and error correction technology, so that the flow meter can be more integrated into the natural environment of industrial production, and the measurement verification is more convenient, economic development, and accurate. The products have reached the excellent level of all countries in the world, and can be used in crude oil, chemical plants, metallurgical industry, power engineering, water supply and drainage and other industries in the market.

Application of ultrasonic flow meter

Ultrasonic flow meter is a non-capacity grid instrument panel, which can not only measure the total flow of materials through a large pipe, but also can be used to measure materials that are not easy to touch and observe.Its measurement accuracy is very high, basically it will not be disturbed by various main parameters of the measured substance, especially when it can handle the strong corrosion, non-conductivity, radioactive material and flammable material that other instrument panels cannot. Difficulties in measuring the total flow of explosive substances.

1. The principle of ultrasonic flow meter

In the whole process of fluid dissemination, the rate of a single ultrasonic pulse generally has a close relationship with the fluid rate, that is to say, the downstream rate exceeds the reverse flow rate. If there is a large time difference in the single pulse dissemination, its total flow will also follow expand.

Therefore, the total flow measurement can be carried out. When carrying out actual operations, both the upstream and downstream controllers all emit a certain ultrasonic single pulse at the launch point, but the two are quite different. The specific performance is that one is upstream and the other is downstream.Suffered from fluid hazards, the time for two single pulses to reach the ultrasonic transducer will also have a certain difference. However, since the two are actually the same way, the difference in transfer time can also mainly show the actual water flow rate of the fluid. When using the time difference method to carry out the measurement, two controllers must be used to transmit points and receive data signals.When the controller is set in the pipeline, the two will implement acoustic data signal communication, and when the work is carried out, the launch point and reception will be carried out.If the fluid in the tube is at a standstill, the spreading time of the downstream and upstream flows remains the same.If the liquid is in a fluid condition, the time for the downstream data signal to spread will be shorter than that of the upstream. In the whole process, when spreading downstream and upstream, the time difference and the actual water flow are shown to be proportional.

2. Features of ultrasonic flow meter

When using an ultrasonic flow meter, there is no need to touch, and there are no blocking parts in the fluid, it is not easy to cause all harm to the flow beam by heat, and it is not easy to cause all working pressure damage, and it can be reasonably applied to different fluids. Especially in the total flow with high viscosity and strong corrosion. In addition, the ultrasonic flow meter can also be used reasonably for gas pressure, and has excellent advantages and characteristics when measuring small-caliber flow.
