Introduction to some common problems of wireless remote ultrasonic water meter
The wireless remote ultrasonic water meter is made by adding a wireless remote water meter module to the ultrasonic water meter. Common remote modules include LoRa modules, NB-IoT modules, etc. The following introduces some common problems of wireless remote ultrasonic water meters:
The wireless remote ultrasonic water meter mainly uses the principle of ultrasonic flow measurement to measure the flow of tap water. The appearance adopts a straight-through pipe section structure design to avoid mechanical wear and tear. At the same time, the wide range avoids the problem of non-measurement of small flow rate of traditional mechanical water meters. For the measurement accuracy of wireless ultrasonic water meters, generally speaking, the allowable error of the first grade of accuracy is ±1% in the high area, and ±3% in the low area, while the allowable error of the second grade of accuracy is in the high area. ±2%, and it is ±5% in the low area. Since the error involves settlement issues, users need to pay special attention when purchasing; If you see a weak current warning symbol on the screen, it means that the power of the water meter is low, and the battery needs to be replaced in time. If the display cannot be displayed normally after replacing the battery, it means that there is a problem with the display, and the user needs to notify the water company for maintenance. Finally, if the wireless remote ultrasonic water meter has inaccurate measurement, it may be caused by three reasons. One is that the water meter is interfered by strong external interference sources, the other is that the pressure of the water supply network is unstable, and the third is that the water meter is in disrepair. The useful life has been reached. When the user encounters the above situation, he should first notify the water department, and then wait for the staff to deal with it. Never disassemble and repair it without permission.
