Product Description

DN15 ultrasonic prepaid water meter with Valve Control LoRaWAN zigbee

Product features: 1. Ultrasonic valve control meter is a new intelligent fully electronic valve control water meter that uses ultrasonic detection technology. This instrument integrates measurement, integration, display, valve control, and MBUS remote transmission. It adopts micro power consumption technology, and the battery can be used for more than 8 years to achieve accurate measurement of the minimum flow rate of 0.001 m3/h. At the same time, the instrument has characteristics such as small size, good stability, and strong anti-interference ability. 2. Adopting ultrasonic flow measurement technology, it can achieve multi angle installation, without affecting instrument measurement, while minimizing pipeline pressure loss. 3. The valve switch can be remotely controlled through NB wireless to achieve remote control of water usage by users. 4. Specially used for household measurement in residential communities

Executive standards:
