LoRa IoT water meter

Introduction:

The LoRa IoT water meters currently available on the market are used to measure water flow in pipelines and also have wireless data transmission capabilities. LoRa water meters use low-frequency narrowband low-power wireless communication technology, utilizing stable and reliable direct spread spectrum technology to ensure consistent communication distance of the water meter. The water meter data is collected by a wireless concentrator and transmitted to the backend meter reading system using mature GPRS/CDMA/3G/4G public network wireless communication, which is cost-effective, stable in communication, and technologically mature. The interior of the watch can effectively prevent water, moisture, attacks, theft, damage, magnetism, interference, and has good confidentiality performance. The water meter components and connectors are made of non-toxic and pollution-free high-quality materials that meet the requirements of water quality and hygiene. They are resistant to water and atmospheric corrosion, have a reliable anti-corrosion layer, and all internal circuits are sealed with epoxy resin (tested to be able to work normally when immersed in water).

When the water temperature is within the specified range of rated working conditions, the maximum allowable error of the volume discharged between the minimum flow rate (Q1) and the boundary flow rate (Q2) is ± 5%;

(b) Maximum allowable error in the high zone:

(9) The maximum allowable error of the volume of flow discharged between the boundary flow rate (Q2, including Q2) and the overload flow rate (Q4):

(a) ± 2% when the water temperature is ≤ 30 ℃;

(b) ± 3% when the water temperature is above 30 ℃;

(10) Accuracy level: Level 2 Pressure loss level: △ p63.

LoRa IoT water meter advantages:

(1) Changed the traditional manual meter reading → billing → charging → urging fee management mode, reduced management costs, minimized the drawbacks of missed, estimated, and erroneous readings, and lowered social production costs; Simultaneously protecting the privacy and security of residents' lives;

(2) The intelligent water meter can accurately determine the usage at each stage through clock design and the use of computer network technology, achieving a "tiered" charging system and promoting the construction of an energy-saving and emission reducing society;

(3) Being able to collect and process data, and perform preliminary processing on the data, is the source of building the Internet of Things and can meet the needs of modern life;

(4) IoT water meters (LoRa) and systems can achieve real-time monitoring of the tested object, changing the traditional method of checking one by one in pipeline leakage control, reducing manpower consumption, improving operational efficiency, and avoiding a large amount of wasteful behavior;

(5) Compared with traditional water meters, it improves the accuracy of measurement and provides a reliable basis for measuring water consumption and ensuring effective water supply for residents;

(6) To achieve multiple functions, the "remote meter reading system" can be used to remotely read meters, query information, provide feedback, prompt information, process and control information for all users. The backend system software can also be used to complete data storage, usage, reporting, printing, fault detection, and achieve a series of tasks such as separate measurement and unified charging of various fees.
