Fully Sealed, Highly Waterproof, And High Protection Level Smart Water Meter For Waterproofing
Waterproof water meters refer to water meters that, through special design, materials and manufacturing processes, can prevent water flow (including splashing, soaking, etc.) from entering the meter housing, thereby protecting the internal precision mechanical or electronic components from damage and ensuring their normal operation.
Application Advantages
- Environmental Adaptability: Suitable for rural water improvement, farmland irrigation, underground pipelines and other scenarios. It can still operate normally even if the well is flooded.
- Low Maintenance Cost: High protection level reduces failure rate. Battery life can reach 6-10 years, reducing replacement frequency.
- Intelligent Management: Real-time monitoring of water usage, supporting leakage detection and remote valve control, improving water management efficiency.
Common water resistance ratings include:
- IP65: Protected against water jets. It can be rinsed with water and will not be adversely affected when exposed to water jets from any direction. Suitable for installation in outdoor areas, corridors, and other environments where it may be splashed by rain or water.
- IP67: Protected against short-term immersion. Under specified conditions, it can be temporarily submerged in water up to 1 meter deep without harmful water ingress. Suitable for installation in underground wells, pits, and other places where short-term water accumulation may occur.
- IP68: Protected against continuous immersion. Under conditions agreed upon by the manufacturer and user, it can operate continuously submerged in water for long periods. This is the highest level of water resistance and is specifically designed for environments where it needs to be installed underwater for long periods, such as deep wells and pools.
When purchasing, be sure to confirm the IP water resistance rating of the water meter and choose based on the installation environment.
Main technologies and methods for achieving water resistance
- Sealing rings and sealant: High-quality rubber sealing rings (such as silicone or EPDM) are used at the junctions of the water meter's casing, glass cover, battery compartment, etc. Sealant is applied at some interfaces for secondary sealing.
- One-piece molded casing: A fully sealed, seamless integrated design is adopted, eliminating water entry points structurally. This is the mainstream design for many smart water meters currently.
- Special interface treatment: For wired remote transmission water meters, professional waterproof connectors are used for the lead wire interfaces. For wireless remote transmission water meters, external lead wires are completely eliminated, fundamentally solving the problem of water entry through interfaces.
- Ultrasonic welding: For plastic casings, ultrasonic welding technology is used to fuse the upper and lower shells together, forming a seamless connection with excellent sealing performance.
- Nano hydrophobic coating: On the reading windows or circuit boards of some high-end water meters, nano coatings are applied to prevent water droplets from adhering, further enhancing safety.
Application scenarios
- IP65: Installation in residential corridors and on walls.
- IP67: Water meter wells, underground pipelines, and areas prone to temporary flooding.
- IP68: Direct installation on water supply pipes and long-term submersion, irrigation wells in farmland, deep well pump rooms, etc.
Summary
Waterproof water meters are indispensable equipment in modern water supply metering systems. The core lies in the IP protection level, which determines the water meter's survival ability in different humid environments. With the development of technology, especially the popularization of non-magnetic sensing and ultrasonic technology, fully sealed and highly waterproof smart water meters are becoming an industry trend, providing a stable and reliable data foundation for smart water management.
