Nb-iot Ultrasonic Water Meter, for residential water meter and AMR, brass tube, DN15-40mm
HOW TO USE
NB-IoT ultrasonic water meter is used for measuring water flow rate through pipe via wireless NB-IoT network upload water consumption
The whole NB-IoT ultrasonic meter reading system consists of ultrasonic water meter, and monitoring management software. The management center can read and monitor water meter accumulated water consumption, instantaneous water flowrate info by NB-IoT network directly.
NB-IoT ultrasonic water meter can set up 3 regular upload days each month, and each timing upload day can set 2 timing uploading clock, and the user can configure time according to the need. During online time, management center can read real-time accumulated water consumption
Applications:
The NB-IoT ultrasonic water meter is used for measuring water flow rate through pipe via wireless NB-IoT network upload water consumption.
Description:
Convectional type, ultrasonic water meter are with built in batch controller and time accumulator. It has extremely low power consumption, stable and reliable performance in long term. All the wet part protection is IP68. The UFM is widely used in municipal water supply, water resource management, industrial water supply, agriculture, irrigation and gardening.
