Rapid Response Rain Gauge


Rapid Response Rain Gauge
Rapid Response Rain Gauge collects rainwater through a standard 100 sq.cm rain collector and then converts this continuously into drops of equal size. These drops are detected by a drop sensor. The rate at which the drops are formed is a function of the rate of rainfall. A crystal time base integrates these drop counts. The time base can be selected to be 10 seconds or one minute. The rate of rainfall is computed from this count by a built in microprocessor and displayed on Liquid Crystal display. A printer output is provided, a proportional voltage output is also provided at the back panel.
