Working principle and maintenance method of tipping bucket rain gauge
The working principle of a tipping bucket rain gauge is as follows: Rainwater enters the water collector from the top inlet, falls into the funnel, and flows into the tipping bucket. When the accumulated water reaches a certain height, the tipping bucket loses its balance and tips over, emptying the water. As rainfall continues, the bucket flips left and right. A contact switch converts the number of flips into an electrical signal, which is sent to the recorder. The precipitation data is read from the cumulative counter and the self-recording clock. This process is repeated to measure the rainfall. Maintenance and care of a tipping bucket rain gauge: Rain gauges typically require monthly maintenance and calibration before heavy rainfall to ensure objective and accurate precipitation measurements. Routine maintenance not only extends the instrument's lifespan but also provides more accurate data. Ensure the outer cylinder is stable and vertical, and the water collector is level, ...
