Product Introduction

The KH.JDW Windproof Tipping Bucket Rain Sensor is a high-precision rainfall measurement instrument designed for coastal, island, and high-wind environments where standard rain gauges are affected by airflow and extreme weather conditions.

It uses a windproof structural design combined with a calibrated tipping bucket mechanism to ensure stable and accurate rainfall measurement even under strong wind interference.

Constructed with 304 stainless steel, the sensor provides excellent corrosion resistance and long-term durability, making it suitable for harsh outdoor meteorological and hydrological observation environments.

It is widely used in meteorological stations, flood early warning systems, coastal monitoring networks, and smart environmental observation platforms, ensuring reliable precipitation data in extreme weather conditions.

How It Works

Rainfall enters through a wind-resistant funnel and is directed into a calibrated tipping bucket. The windproof structure minimizes airflow disturbance, ensuring accurate precipitation capture.

Each bucket tip represents a fixed rainfall value, which is recorded as digital pulse signals for data transmission and analysis.

This ensures:

• Stable rainfall measurement in high wind conditions
• Reduced environmental interference
• Reliable long-term data collection
