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.
Electromagnetic wave wake-up technology: Wake up the target smart meter to make it in the communication state during meter reading, and automatically return to the ultra-low power consumption state after meter reading, saving energy and reducing consumption.
A variety of meter reading methods are available, and wireless centralized reading system and handheld meter reading device meter reading system are selected according to different needs.
Two modes of timed uploading and real-time uploading can be selected to meet different customers’ needs.
High waterproof grade design, the protection grade can reach IP68. Using imported communication chips, it has the characteristics of high performance and low power consumption.

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.
