Hebei Shanghong Meters Technology Co., Ltd. is one of the leading manufacturers and suppliers of nb-iot water meter smart in China. If you're going to wholesale high quality nb-iot water meter smart, welcome to get pricelist and quotation from our factory.
The whole system of NB-IOT water meter is composed of IoT management system platform, NB base station, and IoT water meter (NB-IoT).
The system has a high degree of automation and actively uploads data once a day. However, this can be set according to management requirements, and the operation and consumption of the water meter can be monitored at any time, with a wide range of applications. Low power consumption is an important indicator of IoT water meters, especially suitable for occasions where it is not easy to replace the battery. If you use a battery-powered water meter, it is absolutely unrealistic.
The IoT NB-IoT module has small data volume and low rate. Function, so the power consumption of the NB-IoT module can be very small. The Internet of Things water meter (NB-IoT) has a built-in 6-year communication fee, no renewal is required, so you can use it with confidence.
SHMETERS specializes in the development and production of various caliber IoT water meters.
Product Overview
NB-loT Internet of Things is characterized by strong links, high coverage, low power consumption, and low cost. t is also called the "Narrowband Internet of Things".Because of its very low communication power consumption, the NB-loT wireless remote water meter can continue to work for more than six years without changing the battery. Using the NB-loT wireless remote water meter can realize the wireless automatic meter reading function. At the same time every day, the NB-loT module will collect and automatically transmit the water consumption data of each household to the management platform.Perform statistical analysis and charge for the water consumption of water meters in the managementarea.

Communication method: Comply with the standard NB-IoT protocol and support all Netcom.
Signal antenna: NB-IoT full-band support, in order to ensure that NB-IoT signal can transmit signals normally in severe shielding and interference environment, the antenna of NB-IoT needs to be specially adjusted for the product, and test data should be provided.
Power supply mode: battery power supply, lithium thionyl chloride battery, which needs to meet the service life of 6 years, and the battery can be replaced.
Use of supercapacitors: It is required to use supercapacitors on the water meter equipment to provide a large current for signal transmission to ensure stable signal transmission.
Data reporting: The reporting frequency can be set by the platform, and it is reported once every 24 hours by default. The platform realizes high-intensity data reporting for pipe network data analysis; supports manual data reporting function. NB signal detection: The device side needs to have NB-IoT signal detection function, which can measure signal strength and bit error rate, which is convenient for device deployment and problem analysis.
Valve control function: manual valve control, automatic valve control, valve closing in arrears, abnormal closing, valve opening after renewal, etc., support valve switch in place detection function, to prevent incomplete switching.
Sim card support: micro card is currently supported, and the eSIM function is reserved.
Anti-rust function: It can report the fault information to the cloud service platform in real time, and carry out background linkage processing in time, and at the same time, it is convenient for users to inquire. The water meter valve is automatically switched on and off regularly without affecting the customer's water use to prevent the valve from rusting.
Anti-attack function: When the water meter is attacked by strong magnetism or electricity, it will automatically close the valve to stop the water supply, and automatically record and report the attack, open the reading cover of the water meter, and the valve will open, but when the number of attacks reaches the set value, the platform must be closed Only after authorization can the valve be opened.

Installation Requirements
1. For water meters installed underground, NB signal detectors must be used to detect the signal strength of the surface at the installation location before installation. The signal coverage level must be ≤1. Blind installation may cause the water meter to not upload, and the manufacturer is powerless to solve this problem.
2. The caliber of the water meter should be selected based on the pipe caliber and flow rate being equal to or less than the usual flow rate of the water meter.
3. For newly installed pipes, be sure to wash out the stones, silt, hemp and other sundries in the pipes before installing the water meter to avoid water meter failure.
4. The installation location should avoid sun exposure, freezing, pollution and flooding.
5. The water meter must be installed according to the prompts on the dial. The one marked with "H" is installed horizontally, and the one marked with "V" is installed vertically. The dial faces upward, and the direction of the arrow on the case is the same as the water flow.
6. There should be enough space around the meter installation for the meter installation and debugging and future maintenance. In particular, it is forbidden to seal the watch in a small space. Not only is it inconvenient for you to use, but also the maintenance personnel cannot maintain it, causing trouble to yourself.
7. In order to facilitate daily maintenance, valves should be installed upstream and downstream of the water meter, and the inlet and outlet of the water meter should have straight pipe sections of the same diameter. A straight pipe section of more than 10D should be reserved in front of the meter, and a straight pipe section of more than 5D should be reserved behind the meter.
8. It is recommended to install a filter screen upstream of the water meter to prevent debris mixed into the pipeline from damaging the water meter.
9. The upstream and downstream straight pipe sections should be installed coaxially, and the gasket must not penetrate into the pipe to avoid inaccurate measurement.
10. It is strictly forbidden to artificially shield the wireless communication of the meter.
