rain-intensity gauge

(Also called rain-rate gauge, rate-of-rainfall gauge.) An instrument that measures the rate at which rain is falling.

In the Jardi design, water from the rain collector enters a chamber containing a float with a tapered needle that controls the rate of outflow. The higher the rain rate, the higher the float, and the greater the outflow.
