The NB-IOT ultrasonic water meter uses the time difference between the propagation of ultrasonic waves in forward and backward water to measure the velocity of water flow, and then integrates the flow rate of water flowing through the pipeline
NB-IOT Ultrasonic Water MeterBy utilizing the time difference between the propagation of ultrasonic waves in both upstream and downstream water, the velocity of the water flow can be measured, and then the flow rate of the water flowing through the pipeline can be integrated.
High precision measurementThe ultrasonic measurement technology used, combined with segmented calibration, automatic potential tracking and other technologies, has high measurement accuracy, wide range ratio, and small starting flow rate.
Reliable data communicationData communication adopts narrowband cellular communication technology, which has advantages such as deep network coverage, wide links, and low power consumption. Communication is stable, reliable, and secure.
Multiple monitoring functionsCan monitor water temperature to adjust and compensate for flow rate at different water temperatures; Pressure sensors can also be selected to measure the water supply pressure in the pipeline.
Data storage and reportingTraffic data is frozen every 15 minutes, with 96 freezing points per day. It can be reported periodically, and the reported data includes the cumulative water volume and instantaneous flow rate of 96 freezing points per day in the past month. At the same time, two window opening periods can be configured, during which real-time meter reading can be performed.
alarm functionEquipped with multiple alarm functions such as low battery alarm, air traffic control alarm, flow sensor fault alarm, and abnormal water usage alarm.
display functionLCD display, real-time display of water meter water consumption, instantaneous flow rate, signal strength, water temperature, valve status, step price and other data information.
Other functions：NB-IOT Ultrasonic Water MeterSupport tiered water pricing, respond to national energy conservation and emission reduction policies, and facilitate water price adjustments; Equipped with valve control function, it can realize prepaid function and postpaid water fee payment work according to user needs; Embedding a digital model for repeatedly starting and stopping water usage to solve the problem of dynamic water usage deviation; Bubbles can be detected and identified without affecting measurement accuracy.
Long service lifeNo moving parts, no internal blocking devices, no pressure loss, and powered by lithium batteries with a battery life of over 8 years. Data can be saved for 30 years in case of power failure.
high protection levelFully waterproof process design, with a waterproof rating of IP68, suitable for various harsh environments such as outdoor floors and underground wells.
Easy installation and maintenanceIntegrated structure, beautiful appearance, monitor can rotate horizontally and flip vertically, easy to read; Single key design, easy to operate. Simultaneously providing multiple communication methods, such as calibration and upgrading, can be achieved through infrared or secondary communication interfaces.
