Abstract : A rain rate meter for delineating short-term variations in rain rate having a housing which encloses an electronic balance sensitive to approximately 0.01 grams. The top of the housing is open and has a funnel-shaped element located therein for receiving rainfall. An outlet port is centrally located at the bottom of the funnel-shaped element and a dispersing means is positioned adjacent the outlet port for substantially eliminating the adverse effects of the downward momentum of the rain water flowing from the outlet port prior to being collected by a container which rests upon the balance in the housing. A transfer mechanism is situated in the container in order to gently deposit the flowing rain water into the container. Measurements of collected rainfall weight are made over a preselected period of time by the electronic balance in order to accurately ascertain rain rate. (Author)
