Product Introduction
The KH.WFH float water level gauge (with water level display) is a digital sensor that combines mechanical and electrical technology to achieve accurate liquid level measurement. The device converts the angular displacement of the output shaft into a digital signal to precisely determine the liquid level height and position.
The instrument consists of a float, wire rope, weight, measuring wheel, sensor, bracket, and output socket. When the liquid level changes, the float rises or falls accordingly, driving the measuring wheel through the wire rope. The encoder on the wheel shaft converts this motion into a corresponding real-time digital water level output, providing stable and continuous monitoring.

Features
• Stable and reliable: Optimized mechanical design ensures long service life, excellent anti-interference performance, and high operational stability.
• High precision: Provides a measurement accuracy of ≤±2cm or 0.2% F.S with fine resolution and a large measuring range.
• Power-off memory: Built-in tracking and memory function maintains accurate water level data even after power interruption.
• Multiple output options: Supports parallel Gray code, 4–20mA analog, RS485 serial, or SSI Gray code output for flexible system integration.
• Durable materials: Stainless steel measuring cable and corrosion-resistant float suitable for harsh environmental conditions.
