Product Introduction

The KH.LBRD Long Range Radar Water Level Sensor is a high-precision non-contact level measurement device designed for continuous monitoring of rivers, reservoirs, groundwater wells, industrial tanks, and liquid storage systems.

Using advanced radar ranging technology, the sensor measures liquid level without direct contact, providing stable and accurate measurement performance in challenging environments affected by waves, heavy rain, sediment, foam, dust, and temperature variations.

Compared with traditional contact-based level sensors, the KH.LBRD eliminates corrosion, mechanical wear, and maintenance issues, making it suitable for long-term deployment in both hydrological and industrial applications.

The radar level sensor is widely used in:

• River and reservoir water level monitoring
• Hydrological observation stations
• Groundwater monitoring systems
• Industrial tank level measurement
• Flood monitoring networks
• Smart water IoT platforms

The KH.LBRD provides reliable real-time level data for water resource management, industrial automation, and intelligent monitoring systems.

How It Works

The KH.LBRD uses radar ranging technology to measure the distance between the sensor and the liquid surface.

The radar sensor continuously emits electromagnetic waves toward the target surface. The reflected signal is analyzed to calculate the distance, which is converted into accurate liquid level data.

This non-contact measurement method provides:

• No direct contact with liquid
• No corrosion or sensor fouling
• No mechanical wear
• Stable operation in extreme environments
