JW-YL(YN17) Stainless Steel Tipping Bucket Rain Gauge Sensor is designed for accurate rainfall measurement in meteorological stations, hydrological monitoring, agriculture, forestry, environmental monitoring, and water conservancy projects. It converts rainfall into measurable pulse signals and supports rainfall amount, rainfall intensity, and rainfall duration monitoring.
2. Product Overview
JW-YL(YN17) tipping bucket rain gauge uses a precision tipping bucket mechanism to collect and measure rainfall. Rainwater enters through the stainless steel collection funnel and flows into the tipping bucket. When the collected water reaches the calibrated volume, the bucket tips and triggers a pulse signal. Each pulse represents 0.2 mm rainfall, allowing automatic rainfall data acquisition.
The sensor is built with a 304 stainless steel housing, providing strong durability, high appearance quality, and long-term outdoor reliability. Its unique funnel design helps prevent debris from blocking the water outlet, while the finely manufactured tipping bucket support system ensures low friction, sensitive tipping action, and stable performance.
With optional pulse, 4–20mA, and RS485 Modbus RTU outputs, the sensor can be integrated into weather stations, hydrological telemetry systems, smart agriculture platforms, flood monitoring stations, and environmental data acquisition systems.

FAQ
Q
1. What is this tipping bucket rain gauge used for?
A
It is used to measure rainfall amount, rainfall intensity, and rainfall duration for weather stations, hydrology, agriculture, forestry, and environmental monitoring projects.
Q
2. How does the tipping bucket rain gauge work?
A
Rainwater enters the collection inlet and flows into the tipping bucket. When the bucket reaches the calibrated volume, it tips and outputs one pulse signal.
Q
4. Can JW-IoT provide RS485 Modbus RTU output?
A
Yes. JW-IoT can provide the RS485 Modbus RTU version for integration with RTUs, data loggers, IoT gateways, and cloud monitoring platforms.
Q
5. What is the rain collection diameter?
A
The rain collection diameter is φ200 mm.
Q
6. Is the sensor suitable for outdoor installation?
A
Yes. The stainless steel housing and IP65 protection make it suitable for long-term outdoor rainfall monitoring.
