The NB-IoT ultrasonic water meter directly uploads the data to the meter reading master station through the operator network, without installing a concentrator. The frequency band authorized by the operator is used, and there are very few interference sources, which ensures the stability of communication.
Features of NB-IOT Ultrasonic Water Meter
◇ Strong link
In the case of the same base station foundation, the access times of ultrasonic water meters with NB-IoT wireless transmission function are increased by 50-100 times compared with ultrasonic water meters using other existing wireless technologies. It can support 100,000 connections and can achieve low latency sensitivity, ultra-low equipment cost, low equipment power consumption, and optimized network architecture.
◇ Wide coverage
NB-IoT has strong indoor coverage capabilities, so NB-IOT ultrasonic water meters can not only meet the needs of wide coverage in rural areas but also apply to places that require deep coverage, such as factories, underground garages, manhole covers, etc.
◇ Low power consumption
Low power consumption is an important indicator for IoT applications, especially for some devices and occasions where batteries cannot be replaced frequently. NB-IoT ultrasonic water meter focuses on small data volume and low-speed applications, so the power consumption of NB-IoT ultrasonic water meter can be very small, and the battery life of the device is also greatly improved.

NB-IoT Ultrasonic Water Meter Application Scenarios
1. New housing, old households, renovation of old households, and other environments that need to change the original meter position
Advantage:
a. The original surface is installed on the table and does not require any other plumbing changes and construction.
b. You can only replace the bad table, and you can replace a piece of data without forcing all tables to be replaced in batches.
2. The newly built residential area under the self-control of the property needs to report the environment with the number on the equipment list scattered
Advantage:
a. Only the report form is installed, and all meters do not need to be installed and debugged in advance. Install a watch and upload the data of a watch.
b. It can realize functions that are convenient for management, such as prepayment.
3. Environments with long distances between epitopes such as villa area
Advantage:
a. Installing the table in the original table position does not require too much construction and wiring.
b. The meter has its own upload function, and there is no need to install any additional acquisition equipment to ensure signal transmission.
4. Other environments
Advantage:
As long as other communication methods can meet the environment, the Internet of Things meter can be installed in the original meter position when the signal value is satisfied, and there is no need to install any additional equipment.
