RAIN GAUGE












The most common rain gauge is the ordinary rain gauge, which simply consists of a collector place above a funnel that leads into measuring cylinder, where the rainwater is stored between observations. The measuring cylinder is specially graded to give the rainfall measurement in mm. Alternatively, where rainfall can be particularly heavy, a large container is used to collect the rainwater. Readings are made by pouring the rainwater out of the container into measuring cylinder so that the rainfall could be measured.
