Ultrasonic water meter working principle
The ultrasonic water meter adopts the time difference method to measure the flow. That is, an ultrasonic transducer is installed at the upstream and downstream of the measuring channel (pipe section) to transmit and receive ultrasonic signals.
Because the ultrasonic signal and the water flow signal are superimposed, the propagation speed of the sound wave is different in the forward and reverse flow. Therefore, the running time of the ultrasonic signal emitted by different transducers in the water is different. The fluid can be calculated by measuring the difference of the time The flow rate. Then it is converted into a flow rate, so as to realize the measurement of the flow rate.
There are two transducers on the top of the flow tube. Transducer A transmits an ultrasonic signal to transducer B (downstream), while transducer B transmits an ultrasonic signal to transducer A (countercurrent). Downstream and The countercurrent ultrasonic signal forms a certain time difference in the transmission process. In the case of the calibrated cross-sectional area of the pipe diameter and the length of the standard measuring pipe, the flow rate of the meter is calculated by the calculation chip on the integrator.
Advantages and disadvantages of ultrasonic water meters
Ultrasonic water meter is a fully electronic water meter manufactured with industrial-grade electronic components using the principle of ultrasonic time difference. Compared with mechanical water meters, it has the characteristics of high accuracy, good reliability, wide range ratio, long service life, no moving parts, no need to set parameters, and installation at any angle.
The ultrasonic water meter has no moving or blocking parts in the tested pipeline, no wear, and low pressure loss. High sensitivity, can detect small changes in flow rate. At the same time, it has almost no requirements for the measured medium, has an extremely wide range ratio, and the ultrasonic water meter has a simple structure and is easy to maintain, which is very suitable for civil and industrial measurement.
But the stability of ultrasonic water meters is low.

FAQ
Are ultrasonic flow meters accurate?
The measurement accuracy of the ultrasonic flowmeter is very high. Almost no interference from 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 other instruments cannot.
So what causes the inaccurate measurement of the ultrasonic flowmeter? The following are the reasons for the inaccurate measurement:
The influence of pipeline parameter equipment on the accuracy of ultrasonic flowmeter measurement.
The influence of upstream and downstream straight pipes on the accuracy of ultrasonic flowmeter measurement.
The influence of couplant on measurement accuracy.
The influence of the installation position of the ultrasonic flowmeter transducer on the measurement accuracy.
What are the different types of ultrasonic flow meter?
Common types of ultrasonic flow meters
①According to the measurement principle. Ultrasonic flowmeters are now the most commonly used methods for measuring flow rates are the propagation velocity difference method ultrasonic flowmeter and the Doppler frequency shift method ultrasonic flowmeter. The propagation velocity difference method can be divided into three types: time difference method, phase difference method and acoustic cycle frequency difference.
②According to the installation method of the transducer. There are two types of ultrasonic flowmeters: fixed ultrasonic flowmeter and portable ultrasonic flowmeter.
The transducer installation methods of the fixed ultrasonic flowmeter can be divided into:
A tube-segment ultrasonic flowmeter integrating transducer and measuring tube;
The external clamp ultrasonic flowmeter with the transducer clamped on the outer wall of the measuring tube;
Plug-in ultrasonic flowmeter in which the transducer passes through the outer wall of the pipe and directly contacts the medium;
The transducer is attached to the inner wall of the large pipeline ultrasonic flowmeter.
③According to the channel of propagation. Ultrasonic flow meters can be divided into single-channel ultrasonic flow meters and multi-channel ultrasonic flow meters. Among them, multi-channel can be divided into two-channel ultrasonic flowmeter, ultrasonic flowmeter, four-channel and eight-channel ultrasonic flowmeter.
