Experience with Rain Gauge by Furkan Pathan.

» Rain gages have been designed as meteorological tools to measure the amount of typical precipitation reaching the ground, unobstructed by surface effects.

» Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside. The funnel is 10 times the cross-sectional area of the tube.

Rainfall as low as . 01 inches can be measured with this instrument.

» The sum of daily rainfall calculated from rainfall records equates to total annual rainfall. Knowing the average rainfall for an area helps farmers make decisions about planting, harvesting, and irrigating crops.

» Measuring cylinder rain gauge: Glass measuring cylinder only for rain gauge. Graduated to measure from 0 to 10mm of rain from a 5 inch rain gauge.
