High quality rain gauge has a clock circuit, which can query up to 10 register content. The tipping rain gauge's shell is made of 304 stainless steel, with strong anti-rust ability and good appearance quality. SISCO tipping bucket rain gauge can be used in weather stations, hydrology stations, agriculture and
forestry.
Tipping Bucket Rain Gauge with Level Calibration
- The chassis is equipped with an internal leveling bubble, allowing for precise adjustment of the bottom corners to ensure the device is properly leveled during installation.
- When the rain gauge is placed on uneven ground, the built-in leveling bubble allows for fine adjustments to stabilize the unit.
- Maintaining a perfectly horizontal position is critical for ensuring that rainfall enters the collection funnel evenly. The integrated leveling system ensures that the rain gauge remains properly aligned, leading to more accurate and reliable precipitation measurements.
- Even slight tilting can lead to water spilling, splashing, or bypassing the measuring mechanism entirely. By ensuring the rain water gauge remains level, the system eliminates one of the most common sources of error in rain measurement, ensuring consistent and trustworthy results.
The Tipping Rain Gauge Adopts a Three-dimensional Streamlined Design
- Three-dimensional streamlined structure improves drainage efficiency, ensuring that rainwater flows cleanly through the tipping bucket with minimal splashing or residue.
- Smooth internal surfaces make cleaning and maintenance easier, reducing the chance of sediment buildup and ensuring long-term measurement accuracy.
- The optimized shape allows rainwater to collect and pour evenly, ensuring that each tipping event reflects a precise volume and minimizes partial or premature tipping, which can cause measurement errors.
- With smooth interior surfaces and no sharp corners, the rain gauge can be quickly rinsed or wiped clean. This lowers maintenance time and helps maintain long-term accuracy in outdoor environments.

Q1: What is a rain gauge?
A1: A rain gauge is a meteorological instrument designed to accurately measure the amount of rainfall over a set period, usually recorded in millimeters or inches. It collects rainwater in a funnel or container, allowing for precise quantification of precipitation, which is vital for weather forecasting, agricultural planning, water resource management, and environmental research. There are several types of rain gauges, including manual gauges that require periodic reading, tipping bucket gauges that automatically record rainfall by counting bucket tips, weighing gauges that measure the weight of collected water, and advanced optical or radar-based gauges that estimate rainfall remotely.
Q2: Why a rain gauge is important?
A2: A rain gauge is important because it provides accurate and reliable measurements of rainfall, which are essential for weather forecasting, managing water resources, agriculture, and flood prevention. By tracking precipitation levels, rain gauges help farmers optimize irrigation, enable meteorologists to predict storms and droughts, support water authorities in managing reservoirs and flood control, and contribute to climate research and environmental monitoring. Without precise rainfall data, it would be much harder to make informed decisions that protect communities and sustain ecosystems.
Q3: Can a rain gauge be any size?
A3: A rain gauge can come in various sizes, but its dimensions must be carefully designed to ensure accurate and reliable measurements. Larger gauges can collect more rainwater and are often used in professional or research settings, while smaller, more portable gauges are convenient for personal or educational use. However, the size of the collection area affects the sensitivity and precision of the readings, so rain gauges are typically designed following standard dimensions to balance ease of use with measurement accuracy.
Tips: What are the types of rain gauges?
The common types of rain gauges include:
- Manual Rain Gauge (Graduated Cylinder): A simple funnel and measuring tube where rainfall is collected and read manually.
- Tipping Bucket Rain Gauge: Contains a small bucket that tips when filled to a set volume, triggering a sensor to record each tip automatically.
- Weighing Rain Gauge: Measures the weight of collected water to calculate rainfall, offering high accuracy and the ability to measure snow.
- Optical Rain Gauge: Uses infrared or laser beams to detect raindrops as they pass through a sensing area, providing non-contact measurements.
- Radar Rain Gauge: Employs radar signals to estimate rainfall over a large area without direct contact with rain.
