Rural-specific water meters are intelligent metering devices designed specifically for the characteristics of rural water usage environments. They mainly address issues such as decentralized water supply, harsh conditions (such as humidity and low temperatures), and high management costs.

• Waterproof and moisture-proof: Rural water meters are often installed in outdoor wells or open-air environments and need to reach IP68 waterproof level, capable of long-term immersion or resistance to rain erosion.
• Anti-freezing design: Dry-type mechanism, thickened glass and insulation materials are adopted, with a low-temperature resistance of up to -30℃, to prevent freezing and cracking in winter.
• Corrosion resistance: Materials are mostly cast iron or engineering plastics, suitable for rural water quality with poor conditions (such as sediment and impurities).

• Prepaid function: IC card or Internet of Things water meters support "pay first, use later", reducing the difficulty of collecting fees.
• Remote meter reading: Data is transmitted remotely through NB-IoT/LoRa technology, solving the problem of difficult meter reading in rural households.
• Leakage monitoring: Real-time alarm for abnormal flow (such as pipe leakage), reducing water resource waste.

When choosing water meters for rural areas, it is necessary to comprehensively consider the budget, management requirements and local environment.

1. If the budget is limited, the primary goal is to solve the charging problem:

   The first choice is the "IP68-rated IC card prepaid water meter" (dry core). It can effectively cope with the damp environment underground and achieve "pay first, use later".

2. If you want to achieve modern and efficient management and have the corresponding budget:

   It is strongly recommended to choose the "IP68-rated Internet of Things water meter (NB-IoT)" (dry or ultrasonic core). This is a one-step solution that can greatly improve the efficiency of water supply management and service level, and provide the greatest convenience to users.

3. When making a specific purchase, be sure to confirm the following points with the supplier:

   • Protection level: Does it reach IP68?
   • Core type: Is it a dry core?
   • Range ratio: Is it wide enough (such as R80 or R160) to ensure the accuracy of small flow measurement?
   • Battery life: What is the promised battery life of the smart water meter?
   • After-sales service: Are there technical support and service outlets in the local area?

In summary, the core of the special water meter for rural areas is "durable, reliable and profitable (referring to helping water suppliers collect fees smoothly)". Under the current technological conditions, smart water meters (especially Internet of Things water meters) are undoubtedly the best tools to improve the management and service level of rural water supply.
