Definition and Basic Components

1. IoT-based gas meters: These use a diaphragm gas meter or ultrasonic gas meter as a base meter, equipped with IoT wireless communication modules, microcontrollers, and other components to support remote data transmission and intelligent control.

2. Conventional gas meters: These primarily include mechanical diaphragm gas meters and IC card meters, relying on roller counters or IC card chips for metering and requiring manual meter reading or card top-up.

Core Difference Comparison

1. Technical Principle

● IoT-based meters: These communicate with the gas company system in real time via NB-IoT/C/G network base stations, enabling two-way data transmission.

● Conventional meters: These use mechanical counters or IC cards for one-way data writing and lack remote communication capabilities.

2. Functional Features

● IoT Meters: Remote meter reading, automatic valve shutoff (for abnormal flow/long periods of inactivity), mobile payment, gas usage data analysis, and leak alarm linkage.

● Standard Meters: Displays only accumulated gas volume; IC card meters require card recharge and lack real-time monitoring.

3. User Experience

● IoT Meters: Automatically deposit gas volume into your account 24/7, supports WeChat/app payment, and requires no card insertion or manual intervention.

● Standard Meters: IC card meters require a "press a button, then tap the card" button to recharge; standard meters require manual meter reading before payment.

Pros and Cons

1. Gas IoT Meter

● Advantages: Reduces labor costs (reduces meter reading workload by 90%), improves gas safety (automatically shuts off valves for abnormal flow), and supports smart home integration.

● Limitations: Depends on network signal stability, resulting in high initial installation costs.

2. Standard Gas Meters

● Advantages: Simple structure, low failure rate, no network dependency.

● Disadvantages: Risk of gas theft, manual meter reading can be disruptive, and IC cards can be easily lost or damaged.
