What is the resolution of tipping bucket rain gauge?
The tipping bucket rain gauge is widely used to measure rainfall and has a simple, effective design. Its design typically comprises a specially engineered tipping bucket paired with sensors.
The resolution of a tipping bucket rain gauge is the smallest rainfall amount it can reliably detect and record. This rain gauge collects rainwater in a bucket. The bucket tips over when it reaches a set volume.
The amount of water needed to trigger the tipping action is set in advance. This value sets the resolution.
In most standard models, the resolution is about 0.2 millimeters (mm). Each tip equals 0.2 mm of rainfall. However, more advanced versions can be more precise. They can measure in smaller steps, like 0.1 mm.
In summary:
It’s worth noting that actual resolution can vary.
It depends on gauge build quality, operator skill, and environmental conditions.
These factors may slightly affect measurement accuracy.
