Product Overview
NB-loT Internet of Things is characterized by strong links, high coverage, low power consumption,
and low cost. It is also called the "Narrowband Internet of Things". Because of its very low communicationpower consumption, the NB-loT wireless remote water meter can continue to work for more than six yearswithout 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 andautomatically 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.
The NB-loT system consists of the NB-loT management system platform, base stations, and loT watermeters (NB-loT). The system has a high degree of automation, can monitor the operation and consumption of the meter at any time, and has a wide range of applications.
Technical Features

Two-way authentication;
The air interface is strictly encrypted;
Dedicated channel, no other signal interference, and more stable data transmission
2. Wide coverage
20db gain, coding gain;
lmproved narrowband power spectrum density;
lt has a retransmission mechanism when automatic transmission fails;
China Mobile/Telecom's NB-loT base station has achieved full coverage
3.Low power consumption
Battery life of more than 6 years (1 day/1 communication);
Simplify protocol and chip micro power consumption;
High functional efficiency;
Short transmission/reception time;
4.Big connection
High frequency increase efficiency;
Small packet data sending characteristics;
Very low activation ratio of the terminal
5.Product implementation standards
ISO9001; GB/T778.1.2.3-2007; JG 162-2009;CJ/T 188-2004.
Product Features
1.Periodic report: report the 24 hours data of the previous day, and the data includes daily freezinginformation.
2.High-frequency periodic reporting: The sending frequency can be set or changed through the platform ,and the minimum reporting period is every hour
3.Intensive data collection:4 hours from the set start time, one point every 5 minutes, a total of 48 points of accumulated flow.
4.Data repackaging: When data reporting is unsuccessful, the data will be automatically re-reported inthe next reporting period, and data within the effective storage range can be re-reported.
5. Discrete setting: Discrete the reported time points randomly through the program, the minimumestimated length is 10S, and the default is 0 to 8 points to ensure that the communication basestation will not be blocked by a large amount of data in a short time.
6.Remote setting of parameters: Through the near-end handheld infrared reading device and
communicating with the management platform, setting IP, port and other parameters
7. Alarm function: When the battery undervoltage is lower than the predetermined value, the platform will automatically alarm to remind the administrator
8. Time proofreading: When the data is reported periodically, the clock will be automatically proofread with the platform to ensure the accuracy of the time
Software Advantages
1. Power supply: DC 3.6V;
2.Battery capacity and life: 8500mAh can be used for more than 6 years (automatically uploaded once a day)
3.Static power consumption: ≤10uA Communication power consumption: ≤18uA
4. Working temperature: cold water meter: (0.1~30)℃ hot water meter: (0.1~90)°℃;
5.Working pressure: s1.OMPa;
6. Pressure loss:≤o.063MPa;
7.Shell protection grade: IP68;
8.Sensitivity level of flow profile: U10/D59.
9.Installation environment: Class B;
10.Electromagnetic environment: E1- residential, commercial and light industry;
1.Water meter with proper calibre should be choosed according to diameter of pipeline at installation site. The expected flow rate should be compatible with the Q1 to Q3 flow of the water meter.
2. The water meter installation must be based on the water meter
dial on the prompt: there is "H" logo for horizontal installation, "V" for vertical installation, the direction of the arrow on the body is consistent with the direction of the pipe flow.
3.The front end and the end of the water meter need to be equipped with a shut-off valve, and the straight pipe section of sufficient length and the same diameter is installed according to the requirements of U5, D3 (5DN, 3DN) to ensure accurate measurement.
4.The impact and vibration of the surrounding environment of the installation site should be prevented, otherwise the water meter will be damaged.
5.The water meter should be protected from excessive stress caused by pipes and fittings. If necessary, install the water meter on the base or bracket. The upper and lower water pipes should be properly fixed to prevent any part from being displaced by the thrust of the water when the water meter is removed or the side is disconnected.
6.Pipeline installation should leave the necessary water meter connection length, when the distance between the two ends of the pipeline exceeds the length of the water meter, the pipeline spacing should be corrected to meet the water meter connection length.
7.The main pipeline should be flushed before installation to prevent stones, sand and other debris from entering the water meter.
8.In order to allow the water meter to work for a long time, the water meter should always be filled with water, it is recommended that the outlet faucet is higher than the water meter by more than 0.5m.
9.When using the water meter, measures should be taken to prevent unfavorable hydraulic conditions (cavitation, surge, water hammer) from damaging the water meter.
10.The water meter should be protected from exposure and freezing, and antifreeze measures should be taken during freezing. The water meter should prevent the external environment from corroding and causing damage to the water meter.
11. During the long-term use of water meters, periodic inspections should be carried out according to local requirements. If there are debris, rust and other deposits in the pipeline blocking the water filter network and affecting the accurate measurement, it must be recalibrated by the designated department, and the user shall not repair the water meter at will.
12.If the water meter is used in a harsh environment, after installing the check valve and venting the gas in the back pipe of the water meter, the water meter rotation cannot be eliminated. The water supply enterprise should consider other methods to solve this problem.
The platform adopts the B/S architecture design method, no need to install the client, in the place whereyou can access the Internet,you can log in to the system by directly entering the URL,which is convenient and fast.
1.Perfect remote parameter setting and management control
2.Multiple billing methods and types, a variety of table format output, and can provide user customizationfunctions
3. With user password protection, multi-level operation management, high socurity and confidentiality
4. Data analysis function, daily statistics,monthly statistics, and statistical report output
5. Diversified data interface docking can be seamlessly docked with the current software management platform of the water management department
You need a good solution for water metering---Catering all your needs.
As the China's professional manufacturer and distributor since 2013, we have developed a comprehensive water meter range and a complete solution for the Commercial ,agriculture, Industrial and Domestic market on Mechanical type water meter and smart water meters. Moving with the changes in technology and precision metering has been the mission of the company since its genesis and we are adding metering that can support water sustainability using. Since 2017, we start the export smart water meters to the whole world, and hope more and more countries and region people can save the water with us together with the smart technology and system. Nowadays, S.H.Meters have already become one the main important exporter for water flow meters in China.
We will provide your product to your hand in timely manner and keep you informed of process with your order throughout the whole sales. From the strictly QC inspection, strictly cost control and five star quality services, we believe that you will own a more solution on water metering.
