Hybrid rain gauge

The latest weighing technology in a compact footprint, combined with a self-emptying, monolithic precision tipping bucket, enables outstanding resolution and accuracy. The precipitation sensor measures precipitation amount and intensity. The precipitation sensor combines the advantages of weighing technology with a self-emptying, monolithic precision tipping bucket. This achieves high resolution and precision with a significantly smaller overall volume. The rain gauge thus has higher resolution and precision than conventional precipitation sensors using the tipping bucket measuring principle and is also significantly smaller than conventional weighing sensors because no collecting container is required. The main sensor is a high-precision load cell with overload protection. Its temperature coefficient is determined, if necessary, using a temperature sensor inside the housing. The reed contact pulses triggered by tipping the tipping bucket are used to correct errors during periods of high precipitation intensities. In addition, the self-emptying mechanism of the tipping bucket allows for uninterrupted weighing.
