How accurate are digital rain gauges?
A wireless or digital rain gauge is more accurate than analog models, which may only bear markings in 1/4-inch intervals. However, some premium models are accurate to 1/100 of an inch. A wider diameter usually leads to more accurate readings.
What is the most accurate type of rain gauge?

How do digital rain gauges work?
As rainfall fills the tiny bucket, it becomes overbalanced and tips down, emptying itself as the other bucket pivots into place for the next reading. The action of each tipping event triggers a small switch that activates the electronic circuitry to transmit the count to the digital display.

How far does 1 inch of rain penetrate the ground?
between 6 and 15 inches deep
One inch of water should penetrate the soil somewhere between 6 and 15 inches deep. But your soil type can dramatically affect this. Clay soils, which are denser, won’t be as deeply penetrated by a 1-inch rain event as loamy and sandy soils.
Does the size of a rain gauge matter?
Rain gauge size determines the repeatability and also the accuracy of a rain gauge. The larger the opening, the lower the statistical error in measurements in real-world applications. Always choose the largest size that your budget allows.
Where should a rain gauge be placed to be the most accurate?
To assure an accurate reading, the rain gauge should be placed in an open area away from trees, the house, and other outbuildings. Position the rain gauge twice as far away as the height of a tree or other object and be sure to empty it after every rain shower.
Are you supposed to empty a rain gauge?

Why does a rain gauge need a funnel?
The rain gauge works by capturing and collecting rain water into the funnel. The funnel empties the rain water into the cylindrical cup below. The shape of the funnel also helps keep out unwanted debris such as leaves. The water sitting in the cylindrical cup is accumulated rainfall total.
Does the diameter of a rain gauge matter?
How far should rain gauge be from house?
The rain gauge should be installed at a reasonable distance away from obstacles such as buildings and trees. For example, if a tree is 40ft. tall (taller than a two story house) the gauge should be placed at least 80ft. downwind from it.
