The IoT water meter is an intelligent metering device that combines traditional mechanical water meters with modern communication technology. It transmits water usage data to a management platform through wireless communication technology, enabling remote monitoring and automated management of water meters. Below is a detailed introduction:
Working Principle
– Measurement: The IoT water meter primarily has two measurement methods: mechanical + electronic conversion and fully electronic. The former converts mechanical rotation into electronic pulse signals through magnetic coupling; the latter directly generates electronic signals using ultrasonic flow measurement or electromagnetic induction principles.
– Data Transmission: The water meter is equipped with a communication module, commonly using NB-IoT, LoRa, 4G/5G, etc. For example, with NB-IoT, the communication module packages the processed data and sends it to the NB-IoT base station, which then transmits it to the water service cloud platform.
– Intelligent Processing: The water service cloud platform analyzes the received data, enabling functions such as data storage, statistics, and queries, and sends control commands to the water meter based on predefined rules.
Main Functions
– Remote Meter Reading: Supports daily scheduled reporting and on-demand querying, with data accuracy down to the household level.
– Abnormal Alarm: When continuous flow, short-term high flow, or dry running is detected, the system automatically pushes alerts.
– Remote Valve Control: Equipped with a motorized valve, it can remotely turn the water on or off, suitable for situations like water suspension due to unpaid bills or emergency shutoffs.
– Tiered Pricing: Supports multiple rate settings, enabling precise billing in conjunction with a prepaid system.
Advantages
– Efficient and Accurate: Eliminates the limitations and errors of traditional manual meter reading, improving data accuracy and timeliness.
– Low Power Consumption and Wide Coverage: For example, with NB-IoT technology, battery life can reach 5-10 years, and it can achieve wide coverage, ensuring stable communication even in water meter wells three floors underground.
– Cost Control: The module price is relatively low, making it suitable for large-scale promotion.
Application Scenarios
– New Residential Communities: Can be directly embedded, interfacing with smart property platforms for one-stop management.
– Renovation of Old Communities: No wiring is needed; replacing the original meter allows for remote reading, with quick construction and minimal impact.
– Rural Centralized Water Supply: Dispersed installation with wide signal coverage, solving the difficulties of manual meter reading and billing.
– Industrial Parks and Commercial Buildings: Household metering with real-time monitoring, aiding in energy conservation and consumption reduction.
