Large Diameter Ultrasonic Water Meter GPRS/NB Remote Water Meter
The ultrasonic water meter adopts ultrasonic flow technology, which uses the influence of water flow on ultrasonic propagation to measure flow, and is free from impurities and substantial magnetic interference in water. It has the advantages of convenience, accuracy, stability, and strength. The meter uses high-quality low-voltage electric ceramic transducers to ensure high accuracy and stability. The watch has no mechanical movement, no wear, is not affected by bad water quality, and has low maintenance costs. The meter can be installed horizontally or vertically, and the humanized design meets the requirements of standard reading viewing angles, making reading more convenient.
