Key points for water meter selection are as follows:

1. Meter Characteristics

Measurement Range (Q3/Q1): Selecting a water meter with a wide measurement range can cover more flow scenarios, but reliability must be balanced.

Accuracy Level: General household water meters are rated Class 2, but higher accuracy options (such as Class 1) are available. This should be considered based on actual needs and budget.

2. Water Meter Installation Conditions

Water Quality Adaptability: Dry or liquid-sealed water meters are preferred in areas with poor water quality. Ultrasonic water meters are preferred for water with high impurities.

Hydraulic Conditions: Positive displacement water meters are insensitive to hydraulic disturbances and have low installation requirements. For rotary vane water meters, the length of the straight pipe section should be carefully considered.

Environmental Conditions: Outdoor installations require consideration of temperature, humidity, and electromagnetic interference; water meters with electronic devices must meet IP protection ratings.

III. Functional Requirements for Water Meters

Prepayment Function: Suitable for areas with underdeveloped infrastructure and difficult water bill collection.

Remote Transmission Function: Wired transmission offers high reliability, while wireless transmission (such as NB-IoT) offers greater flexibility. The choice should be based on network coverage.

IV. Types of Water Meters

Mechanical Water Meters: Highly adaptable to environmental conditions and require no power supply, but have limited metering range and functionality.

Remote Water Meters: Offer a wide measurement range and enable intelligent management, but require a power supply and are sensitive to electromagnetic interference.

Ultrasonic Water Meters: No mechanical parts, low maintenance costs, but sensitive to flow fields and require caution in transient flow scenarios.

V. Cost-Effectiveness of Water Meters

Cost: Comprehensively consider procurement, installation, and maintenance costs, while meeting requirements.

Lifespan: Household water meters generally last no more than six years and require regular replacement.
