Tipping Bucket Rain Gauges FAQs
What is a Tipping Bucket Rain Gauge?
A tipping bucket rain gauge is one of the most traditional tools used for weather station applications. These rain gauges include a rain-collecting funnel, two carefully calibrated “buckets” mounted on a fulcrum, and an electronic switch.
How does a Tipping Bucket Rain Gauge work?
A tipping bucket rain gauge has several components that allow it to accurately measure rainfall. As rain falls, it lands in the funnel of the tipping bucket rain gauge. … The top bucket is held in place by a magnet until it has filled to the calibrated amount (usually approximately 0.001 inches of rain).
How is rain fall measured?
Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside. The funnel is 10 times the cross-sectional area of the tube. Rainfall as low as .01 inches can be measured with this instrument.
How average rainfall is calculated?
Annual rainfall is the sum of daily rainfall, that can be calculated from raingauge records. Here, while calculating average annual rainfall one must take the length of period into account. One cannot simply average the 10 years of data to state the average rainfall. It has to be 30-35 years.
How do you calculate rainfall volume?
- Take the dimensions of the footprint of your roof and convert them to inches. (So, a 50′ x 20′ roof is 600″ x 240″.)
- Multiply the roof dimensions by the number of inches of rainfall. …
- Divide by 231 to get the number of gallons (because 1 gallon = 231 cubic inches).
