Benefits of Photoelectric Direct Reading Water Meter
High reliability
No active electronic components are involved in the core metering process; data is collected solely through optical recognition. The service life is the same as mechanical water meters, reaching over 10 years;
Ultra-long battery life
The battery only supplies power during meter reading. Combined with industrial-grade lithium thionyl chloride batteries, the battery life can reach 8-15 years, eliminating the need for frequent replacement;
Strong anti-interference
Unaffected by impurities in the water, external magnetic fields, voltage fluctuations, etc., ensuring strong reading stability;
High compatibility
Can directly replace existing mechanical water meters without modifying the water supply pipes, adapting to both new and old scenarios.
Municipal water supply systems: Remote metering and billing management for residential water use
Industrial water systems: Industrial water flow monitoring and usage control
Commercial buildings: Individual metering and energy management for office/shopping mall units
Smart city projects: Data acquisition and monitoring for smart water systems
Agricultural irrigation: Statistics and remote management of farmland irrigation water use
Two Mainstream Technologies of Photoelectric Water Meters
Transmissive Photoelectric Direct Reading
The register wheel uses an alternating design of transparent and opaque areas. The LED illuminates from one side, and the photosensitive element receives the light on the other side. For example, the number "3" corresponds to 3 light-transmitting holes, and the receiver detects 3 light transmission signals to determine "3". This technology has a simple structure and controllable cost, requiring only basic requirements for the uniformity and cleanliness of the register wheel material, and avoiding obstruction by stains.
Reflective Photoelectric Encoding
The surface of the register wheel is printed with alternating black and white absolute encoding patterns. The LED and receiver are located on the same side. Different numbers correspond to a unique reflected light pattern, and even with partial obstruction, the algorithm can correct and identify the number. It has stronger anti-pollution capabilities, is suitable for complex scenarios with poor water quality, and demonstrates superior technological advancement.
Both technologies are essentially absolute encoding recognition, reading the current actual water consumption each time, rather than the accumulated number of pulses, thus fundamentally avoiding the inherent errors of pulse counting.
