WebSep 25, 2024 · This type of recording rain gauge is also known as a float type gauge. Here, rainfall collected by funnel-shaped collection is led into a float chamber causing the upload to rise. When the float rises, a pen (pointer) attached to the float through a level system records the elevation of the float on a rotating drum driven by a clock mechanism. WebJan 1, 2015 · Using the floating chamber method has two main advantages over the other techniques: it is easy to use and is a low cost technique. Furthermore, the fact that the lakes consist of flat and perfectly homogeneous surfaces makes the CO 2 flux measurements easier than on volcanic soils.
