Wireless remote transmission valve controlled water meter

无线远传阀控水表 is an intelligent metering device that integrates Internet of Things technology and valve control. It achieves real-time transmission of water data and remote valve control through wireless communication. Its core functions and technical characteristics are as follows:
1、 Core technical characteristics
Dual-mode communication architecture
Supports low-power wide area network technologies such as NB IoT/LoRa/4G, data encryption and direct transmission to the cloud, suitable for urban dense areas, rural areas, and underground environments
1. NB IoT has become mainstream due to its strong penetration, ensuring stable signals in underground wells and enclosed spaces.
Valve control linkage mechanism
Automatic valve closing: Automatically close the valve in case of arrears, low battery voltage (≤ 3.1V), magnetic interference attack, or power outage, and ensure the valve closing action is completed instantly through Farad capacitors.
In place detection: Real time monitoring of valve on/off status, reporting platform alarm in case of abnormalities, and forcing on/off valve in case of faults.
High protection and long battery life
IP68 waterproof: No leakage during long-term underwater work, suitable for humid underground environments.
Ultra low power consumption: sleep current ≤ 20 μ A, battery life 6-10 years, combined with dynamic power management to reduce maintenance frequency.
2、 Core functions
Specific implementation of functional categories
Measurement control without magnetic sensing/ultrasonic measurement (accuracy ± 1%), preventing dripping, leakage and water theft; Automatic switching of tiered water pricing.
Security protection magnetic interference automatic valve closure and recording of attack events; Two level voltage warning (can still operate for 3 days after low voltage alarm).
Real time monitoring of water usage/pressure/temperature on remote management platform; Support APP online recharge, usage inquiry, and abnormal water usage warning.
3、 Typical application scenarios
Guardianship for elderly people living alone
An abnormal sudden drop in water usage triggers valve closure and an alarm, and the community is coordinated to intervene in a timely manner.
Commercial prepaid fee management
Merchants who owe fees will automatically stop water supply, and after payment, the valve will be remotely opened (with a synchronous delay of about 40 minutes) to reduce manual collection costs.
Rural underground installation
Fully sealed moisture-proof design+NB IoT wide coverage, solving the problem of meter reading in scattered areas.
4、 Selection and installation points
Communication compatibility: Priority should be given to the three network access (China Mobile/China Unicom/China Telecom) models to avoid signal blind spots.
Valve type: For commercial scenarios, an electric valve control module is required as standard, while for household use, DN15-DN25 with antifreeze is selected.
Installation specifications:
Signal strength should be greater than -115dBm, avoiding metal shielding areas;
An environment without power supply requires the use of DTU to enhance signal stability.
