ABSTRACT:
A heavy rain rate warning indicator having a housing which has a first opening in the top and a second opening in the bottom. A rain collector/feeder is located in the first opening for directing collected rain in a stream onto a flat plate, pivotally mounted within the housing. A predetermined amount of movement of the flat plate causes the activation of a switch which in turn provides a signal to an alarm system indicative of heavy or severe rainfall. In addition, a gear arrangement can be operably connected to a support rod for the flat plate in order to provide instantaneous rain rate information.
