Overview
The YUNYI XY Series Laser Radar Level Meter is a non-contact instrument for continuous level measurement using a semiconductor laser. It emits continuous or high-speed pulsed beams; the time-of-flight between emission and reception is measured to calculate distance to the target.

How It Works
D = C × T / 2
Level = E – D
The onboard processor converts distance into a percentage of the configured range and provides corresponding analog/digital outputs.

Measurement modes

• Pulse method – suited for long-distance general applications
• Phase method – for higher-precision requirements

Key Advantages

• Exceptional beam focus – very small divergence and high directionality; narrow beam minimizes echo from obstacles.
• Extremely long range – configurable from 0.05 to 1000 m with limited blind zone.
• Temperature-independent – measurement not affected by medium or ambient temperature variations.
• Non-contact – no sensor contact with material, reducing fouling and maintenance.
• High speed – rapid response suitable for fast-changing liquid and solid levels.
• High precision – typical accuracy 0.1% with 1 mm resolution.
• Operator interface – programmable with a 4.3-inch touchscreen (Chinese standard interface).
