Product Description
Application:
A high-precision smart meter that uses photoelectric sensors to read wheel digits directly, ensuring zero-error data transmission for remote management.
Key Features:
• Direct Reading: Reads the wheel digits directly with zero cumulative error.
• No Power Needed: Only consumes energy during the instant of remote reading.
• Precision Sensing: Advanced photoelectric technology ensures high data reliability.
• Anti-Interference: Immune to external magnetic fields and mechanical vibrations.
• Long Lifespan: Non-contact measurement reduces wear on internal components.
• Smart Integration: Seamlessly connects to M-Bus or RS-485 systems.
• IP68 Protection: Fully sealed design for stable operation in damp environments.
• Instant Billing: Provides real-time data for accurate and efficient water management.
Specifications:
• Body material: Cast iron
• Accuracy: R80/ R100
• Size: DN15-20-25
• Cold water: 0 ℃ - 50℃ / Hot water 0 ℃ - 90℃
• Water pressure: 1.0MPa / 1.6MPa
• △P≤63
• Connecting threaded option: G/ BSP/ NPT
• Transmission: M-Bus/ RS485
Installation:
• Install horizontally with the register facing up for accurate sensing and reading.
• Keep the communication cable away from high-voltage power lines to avoid interference.
• Ensure all wire connections are properly sealed with waterproof heat-shrink tubing.
