1. Working principle
1.1 Ultrasonic flowmeter is a flowmeter that measures flow by detecting the influence of fluid flow on the ultrasonic beam (or ultrasonic pulse). The ultrasonic flowmeter adopts the principle of time difference measurement. The signal sent by one probe passes through the pipe wall, the medium and the other side of the pipe wall, and is received by the other probe. At the same time, the second probe also sends a signal and is received by the first probe. Due to the influence of medium flow, there is a time difference Δt between the two. According to the calculation, the conversion relationship between the flow rate V and the time difference Δt can be obtained V = (C2 / 2L) × Δt. Then the flow rate value Q can be obtained.
1.2 Ultrasonic water meter is a new type of water meter. It can detect the time difference caused by the speed change when the ultrasonic wave propagates in the water upstream and downstream. And analyze and process the water speed to further accumulate the water flow. Features: Low start-up flow, large range ratio, high measurement accuracy, and stable work. There are no moving parts inside, and no choke elements. And it is not affected by impurities in the water and has a long service life. The output communication function is complete, which can meet various communication and wireless networking requirements. It has excellent small flow detection capabilities and can solve many traditional water meter problems. It is more suitable for gradient charging of water charges. It is more suitable for saving water resources and rational use. It has a broad market and application prospects.
2. The difference between ultrasonic water meter and ultrasonic flow meter
2.1 Ultrasonic flowmeter is a non-contact instrument. It can measure the flow of large-diameter media, and can also be used to measure media that are not easy to contact and observe. Its measurement accuracy is very high, and it is almost free from the interference of various parameters of the measured medium. In particular, it can solve the flow measurement problems of strong corrosive, non-conductive, radioactive, and flammable and explosive media that cannot be solved by other instruments.
2.2 The output communication function of the ultrasonic water meter is complete, which can meet various communication and wireless networking requirements. It has excellent small flow detection capabilities. It can solve many traditional water meter problems and is more suitable for gradient charging of water charges. It is more suitable for saving and rational use of water resources. It has a broad market and application prospects.
Through the above, I believe everyone has seen that the principles of ultrasonic flow meter and ultrasonic water meter are the same. Ultrasonic flow meter is just a large range. The medium it measures may be water, chemical liquids, petroleum, alcohol and other fluids. However, the ultrasonic water meter is only used for water only.
