DESCRIPTION
The 4G remote water meter is an intelligent water meter integrated with 4G wireless communication technology, which can automatically read and remotely transmit meter data to the server, achieving real-time monitoring and management of water resource usage. It is usually composed of a conventional mechanical water meter plus an electronic collection and module, which completes signal collection, data processing, storage, and uploads the data to the repeater or handheld meter reader via the communication line.
WORKING PRINCIPLES
When water flows through the water meter, the metering mechanism inside the water meter measures the water consumption and generates corresponding pulse signals or digital signals These signals are captured and processed by the electronic acquisition and transmission module, and then the data is transmitted to the remote server or management system via the 4G. The management department can view the user's water usage in real time through the background software, including water consumption, water usage time and other information, and carry data analysis and management.
FEATURE
● Low power consumption design:Adopt the advanced electronic technology and optimize management solutions,making the water meters to consume the power very little in normal operation,extending the lifespan of batteries,reducing the replacement frequencies of batteries and maintenance cost.
● Wide coverage:4G network has wide coverage,even in remote areas or basements which is in weak signals,ensuring the water meters to transmit the data of water meters stably.
● High-precision measurement:Utilize advanced sensors and measurement technology, it can measure the water consumption of the user precisely with small error,meet the requirements of different users for measurement accuracy .
● Real-time monitoring: It can monitor the user's water usage in real-time, providing timely and accurate data support for water management departments, facilitating their resource management and scheduling.
● Intelligent management:Support for tiered water price、prepayment functions,the user can check water usage information 、recharge payment via mobile APP 、online business halls.
● Easy installation:There’s no need to wire,easy and fast installation, reducing the difficulty of construction and cost.
