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.
