Product description
The KDIoT series of IoT water meters adopt the current world's advanced narrowband cellular communication technology and wireless digital listening technology, and have the advantages of deep network coverage, wide connectivity, and low power consumption. A brand new remote water meter based on the NB-loT network. The base meter of this water meter adopts a high-sensitivity liquid-sealed mechanical meter with a maximum sensitivity of 160 times; compatible with non-magnetic or magnetic signal acquisition methods; electromechanical separation structure design, It has the characteristics of easy maintenance and IP68 waterproof rating.
NB-loT technical advantages
1. Low power consumption (>10 years)
2. Deep coverage 20dB+ gain (compared to 2G, it penetrates a wall more)
3. Low-cost module
4. Multiple links
5. Security (to ensure the security of customer data)
6. Global unified standards & roaming (reducing costs)
7. Network continuity (guarantee reliable and stable operation of the network)
8. Reuse the existing cellular network (faster deployment time, lower cost)
Application advantage
1. Support multi-operator network transmission: no wiring required, reducing construction costs
2. Support intensive upload mode: the frequency of data upload can be set, and the default data is sent once an hour
3. High acquisition resolution: the resolution can reach 0.001m/h, realizing quasi real-time monitoring of user water consumption, and providing value-added services such as water leakage alarm
4. Frozen water meter data: store the interval flow rate, temperature and other information of the water meter, and the frozen data can be queried and exported
5. The parameters can be configured remotely: various parameters of the water meter can be set through the host computer, such as the interval flow storage interval, the online type, etc.
6. Real-time fault warning information: timely troubleshoot water meter faults, external interference, and abnormal water usage
7. Remote firmware upgrade The water meter can be upgraded wirelessly through the host computer, which is convenient for the upgrade and expansion of the water meter function. There is no need to upgrade or replace the water meter on site.
Application Environment
1. Reconstruction of new buildings and old communities
2. No need to consider the distribution distance of user meters
3. Operators are required to build NB-loT network platform
Function and technical parameters
●The water meter data is reported periodically every 24 hours. The reported data includes accumulated flow. 48 sets of incremental flow data collected and stored every half an hour, daily accumulated reverse flow, daily maximum flow rate, daily maximum flow rate timestamp, battery voltage, Table environmental temperature, etc.
●High-frequency periodic reporting The sending frequency can be changed through the network settings of the NB-loT platform, and the minimum reporting period can be set to 1 hour.
●Large flow alarm The maximum flow can be set, and the alarm will be given when the flow exceeds this flow.
●Set the base number of the water meter By remotely setting the base number, the water meter ensures that the factory electronic readings are synchronized with the mechanical readings of the water meter.
●Set the water meter number by remotely setting the water meter number to ensure that the electronic number of the water meter is synchronized with the water meter number.
