We’ve solved this problem. In fact, we solved it 20 years ago.Our innovative flow control mechanism (siphon) regulates the flow rate into the gauge, correcting intensity errors which all conventional TBRGs suffer from. This mechanism ensures reliable data across multiple rainfall intensities. The TB3 & TB4 deliver outstanding accuracy, ± 2% from 0 to 10 in/hr (0-250 mm/hr) and ± 3% up to 20 in/hr (500 mm/hr).
In fact, the TB4 measured the highest daily rainfall record in the United States.
Non-clogging finger filter
Non-clogging finger filter
Reduces blocking and protects against data loss
Blocking of tipping bucket rain gauges due to the presence of airborne and animal debris is a major threat to the accuracy of rainfall data, especially in remote locations. The TB3, TB4 and TB7 models are fitted with our unique stainless steel vertical finger filter that minimizes blockage, dramatically reducing field maintenance requirements and most importantly protecting against data loss.
