How does the ultrasonic water meter work? How does the ultrasonic water meter work?


 Water meter is the most indispensable product in our home life, ultrasonic water meter, I don't know if you have heard of it, today we will explore the relevant content of ultrasonic water meter.


How about ultrasonic water meter

 Ultrasonic water meter is a fully electronic water meter made of industrial-grade electronic components using the principle of ultrasonic time difference. Compared with mechanical water meters, it has the characteristics of high precision, good reliability, wide range ratio, long service life, no moving parts, no need to set parameters, and installation at any angle.

 

How ultrasonic water meters work

 The ultrasonic water meter uses the time difference method to measure the flow, that is, an ultrasonic transducer is installed on the upstream and downstream of the measurement channel (pipe section) for mutual transmission and reception of ultrasonic signals.

 Since the ultrasonic signal and the water flow signal are superimposed, the propagation speed of the sound wave is different in the forward flow and the reverse flow, so the operation time of the ultrasonic signal emitted by different transducers in the water is different. By measuring the time difference, the fluid can be calculated. The flow rate, and then converted into flow, so as to achieve flow measurement.

 There are two transducers on the top of the flow tube, transducer A transmits an ultrasonic signal (forward flow) to transducer B, while transducer B transmits an ultrasonic signal (countercurrent) to transducer A, downstream and The countercurrent ultrasonic signal forms a certain time difference in the transmission process. Under the condition of the calibrated pipe diameter cross-sectional area and the standard measuring pipe length, the flow rate of the meter is calculated by the calculation chip on the integrator.

Ultrasonic water meter application

1. Industrial process measurement and control.

2. Replace the mechanical flowmeter to improve the measurement reliability.

3. Substitute various types of high-performance flowmeters.


 About the ultrasonic water meter, I will introduce it here. I hope it will be helpful to you. If you want to know more about the ultrasonic water meter product knowledge, please feel free to consult us.
