Product Introduction:

The current intelligent IoT water meters are mainly based on mechanical water meters, and an IoT technology is added on top of this to enable the water meters to quickly achieve remote collection, transmission, management, and storage of water usage data. It is not as unattainable as people imagine, its appearance is similar to a smart water meter, but its functions are more complete. Users and managers can remotely control and manage water usage anytime and anywhere, bringing them a certain degree of convenience in metering, linear smart metering, and smart water usage. At the same time, the IoT wireless remote water meter supports mobile control work, using a mobile APP to directly connect to the water meter, realizing online payment, monitoring, billing, management, analysis, processing, storage and other work, allowing smart water use to accompany everyone anytime, anywhere.

Technical parameters of intelligent IoT water meter:

【 1.1 】 Timed Collection: Record historical data on a scheduled basis according to the set timed data collection;

[1.2] Accurate data reporting, with scheduled and real-time reporting functions, as well as packet replenishment function;

[1.3] Remote reading: Regularly and proactively report and calculate readings;

【 1.4 】 Prepaid: Supports prepaid and pre order quantities, and closes the valve for overdue payments;

[1.5] Warning system: Alarm prompts such as battery undervoltage, abnormal measurement, pre order quantity and prepaid usage reaching threshold, etc., and different emergency water consumption can be set according to different users;

【 1.6 】 Large capacity storage: can freeze data for up to 24 months and 31 days per day;

Step by step water price: Water prices can be set at different benchmark prices and step by step prices based on user categories and usage;

[1.8] Data supplementation function: In case of special circumstances where the current data upload is unsuccessful, the unsuccessful data will be automatically supplemented during the next upload;

Each water meter communicates directly with the server through China Telecom's NB IoT narrowband IoT communication method to complete data uploading, querying, and setting functions;

【 1.10 】 Meter reading data upload time and frequency can be freely set remotely through local and NB IoT narrowband IoT. The water meter automatically reads real-time data when online according to the background settings, and is in sleep mode when no command is executed;

【 1.11 】 Payment and Settlement: Each water meter can be set with three working modes: prepaid amount, prepaid water volume, and postpaid. The settlement method for water meters can be set as monthly settlement, quarterly settlement, or annual settlement;

The water meter can collect real-time cumulative water consumption and other data information through management software, or collect the cumulative water consumption frozen for each day in the past month and the water consumption for each month in the past 24 months.

Advantages of intelligent IoT water meters:

Compared with traditional mechanical water meters, smart IoT water meters do not require much manpower and instead adopt an unmanned approach. Combining NB IoT electronic modules and cloud management control systems, remote water meters are used to achieve remote data collection, transmission, storage, analysis, management, and monitoring. No need for meter readers to manually read meters door-to-door, avoiding problems such as errors, estimations, and missed readings.

From the perspective of water meter technology currently mastered in China's water meter industry, NB IoT technology is very popular. For the first time, it has been applied to tap water measurement, achieving a high water level gauge. With the continuous growth of people's demand for direct drinking water, the water meter will automatically cut off when the purchased water is used up. The three major domestic operators can provide telecom grade security and reliability for NB IoT.

Non contact water meter (RF type) technology adopts non-contact prepaid technology, and data is transmitted wirelessly on the outer wall of the water meter. All electronic circuit contacts and electrodes are fully sealed, without any exposed electrodes, and can work normally immersed in water, completely solving the problems of waterproofing and moisture resistance.
