(See separate web page for measure snowfall .) among the an essential components the the earth’s hydrological cycle is precipitation. Rainfall is crucial for giving the fresh water that sustains life. Some say the very first rain gauge to be invented more than 2,000 years ago when rulers the the Choson dynasty (now Korea) decreed the all towns were to connect in measure precipitation.

There are electronic rain gauges that actions rain fall, and also are also self emptying and frost proof. The an easy idea is the rain collector’s measure spoon being immediately tipped and emptied when the pre-adjusted water weight has actually been reached.

Small units have a funnel measurement about 5 x 10 cm, and also the rain is registered v a resolution of 1 mm. The rain runs with the funnel of the rain collector into a self-emptying spoon which automatically tips and also is cleared as shortly as over there is a particular quantity that water in the rain collector because that which it has been adjusted. The spoon is fitted v a magnet maintained in place by one anchor and also the spoon is cleared by a fast tip – returning immediately to collecting place for repertoire of a brand-new portion that water.

After one millimeter of rain, the spoon will tip and empty, and also the rain loss will be presented on the an equipment that it connected to. That can be a LCD display, data logger or a computer. The data deserve to betransfer over plenty of miles or kilometres, and the measuring technique is an extremely accurate and also with a maxium deviation the +/- 2%.
