JFZ-1 Float Capacitive Rain Gauge
Product Introduction
The JFZ-1 Float Capacitive Rain Gauge is a high-precision automatic rainfall measurement instrument designed for meteorological observation, hydrological monitoring, and precipitation data collection. It adopts a float-type measurement structure combined with a capacitive displacement sensor, enabling accurate detection of rainfall changes.
With a capacitive sensor resolution of 0.1mm, the JFZ-1 rain gauge provides highly accurate rainfall measurement. The instrument uses two electric valves to automatically control water inlet and drainage, allowing the float to drive the capacitive displacement sensor for continuous cyclic measurement.
During rainfall recording, the unique water control design prevents rainfall loss and improves measurement reliability, ensuring accurate precipitation monitoring over long-term operation.

• Accurate detection of small precipitation changes.
2. Automatic Water Control System
• Equipped with two electric valves for automatic water inlet and drainage.
• Prevents rainfall loss during measurement.
• Ensures continuous and stable rainfall recording.
3. Reliable Float Measurement Structure
• Float movement directly reflects rainfall variation.
• Cyclic measurement design improves accuracy.
• Suitable for long-term unattended operation.
4. Large Data Storage Capacity
• Rainfall recording capacity exceeds 5000mm.
• Supports more than 4 years of rainfall data storage.
• Suitable for remote meteorological monitoring stations.
5. Low Power Consumption Design
• Ultra-low static power consumption.
• Suitable for solar-powered and remote monitoring systems.

Working Principle
The JFZ-1 Capacitive Rain Gauge works based on the relationship between rainfall accumulation and float displacement.
When rainwater enters through the precision rain collector, it flows into the measuring chamber and causes the float level to change. The float movement drives the capacitive displacement sensor, which converts mechanical displacement into an electrical signal.
The built-in control system calculates the rainfall amount according to the sensor displacement. Two electric valves automatically manage water intake and drainage, allowing the instrument to repeatedly measure rainfall without losing accumulated precipitation data.
The high-resolution capacitive sensor provides precise rainfall measurement and stable long-term monitoring performance.
