With the progress of the times, the ultrasonic water meters we use are becoming more and more intelligent. Technology makes the meter reading fee smarter. Today’s main prominent ultrasonic water meters can generally be customized according to customer needs. Wired remote ultrasonic water meters, NB-loT ultrasonic water meters There are three types of water meters and LoRa ultrasonic water meters. However, most people don’t know much about these three types, especially LoRa ultrasonic water meters, and few people know about them?


Today, I will introduce to you the LoRa ultrasonic water meter produced by our company. I hope that through the introduction, you will have a better understanding!

The birth of LoRa is earlier than that of NB-loT. LoRa works in unlicensed frequency bands, so no additional fees are required. The LoRa protocol is simpler and easier to develop than NB-loT, and the relative cost is less. LoRa nodes can sleep longer or shorter according to the needs of specific application scenarios, and the battery life is longer.

LoRa Smart Ultrasonic Water Meter: Using advanced wireless transmission technology to achieve remote centralized reading of remote water meters, concentrators, and computers, without wiring, simple and convenient construction, and effectively solve the problem of difficult meter reading.

The remote water meter utilizes the wireless networking of the meter. Signal coverage without gaps. No meter reading blind spots, valve anti-rust function design. The valve can be opened and closed automatically.

Frequency automatic calibration technology: automatic adjustment of operating parameters. Effectively avoid frequency offset caused by environmental changes. Achieve super high meter reading rate.

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.

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.

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;
Insertion Type Ultrasonic Flow Meter 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.

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

Because the ultrasonic signal is superimposed with the water flow signal. Make the sound waves travel at different speeds in the forward and reverse flow. Therefore, the ultrasonic signals emitted by different transducers have different running times in water. By measuring the difference in time, the flow rate of the fluid can be calculated. And then converted into flow, so as to achieve flow measurement.

The advantages of ultrasonic flowmeters are:

  1. Ultrasonic flowmeter is a non-contact measuring instrument, which can be used to measure fluid flow and large diameter flow that are not easy to touch and observe. It does not change the flow state of the fluid, produces no pressure loss, and is easy to install.
  2. It can measure the flow of strong corrosive medium and non-conductive medium.
  3. The measurement range of the ultrasonic flowmeter is large, and the diameter of the pipe ranges from 20mm to 5m. 4) The ultrasonic flowmeter can measure the flow of various liquids and sewage.
  4. The volume flow measured by the ultrasonic flowmeter is not affected by the thermophysical parameters such as temperature, pressure, viscosity and density of the measured fluid. Can be made into fixed and portable two forms.
