The funnel increases the area of catchment and makes the reading more accurate by increasing the volume of rain collected. Rainfall statistics must be standardised by specifying the mouth diameter of the funnel if the reading is to have any value.

What is the function of funnel on the rain gauge?
The funnel increases the area of catchment and makes the reading more accurate by increasing the volume of rain collected. Rainfall statistics must be standardised by specifying the mouth diameter of the funnel if the reading is to have any value.
What is a rain-gauge made up of?
It is made up of the, funnel, measuring cylinder,beaker and a copper cylinder.
What is a rain gauage?
A rain gauge is a device used to measure the amount of rainfall in a specific location. It is typically a cylinder or funnel-shaped container with markings or measurement lines on the sides to indicate the amount of precipitation. When rain falls into the gauge, it collects in the container, allowing for accurate measurement.
Why does one inch in an official rain gauge actually only one - tenth of an inch of rain?
If the rain gauge has a 10:1 ratio as described, then the funnel on top has an area that is 10 times the cross-sectional area of the glass tube. Suppose you had a can, that has the same area opening as the funnel, then if it rains 0.5 inch that day, there will be 0.5 inches of water in the can, but if you take the water in that can and pour it into the rain gauge (with cross sectional area 1/10 of the can), that same volume of water will fill up the gauge by 5 inches. They do this so that it is easier to read the amount of rain. If you did not have the funnel on top, it'd be harder to read how much rain there was (was it 0.1 inches or 0.15 inches for example), plus statistically a smaller opening has less of a chance of 'catching' a raindrop than the wider opening.
What is the technology that shows the form amount and location of precipitation?
It is an ancient weather instrument called a rain gauge. A funnel is inserted into a tube. A measurement of 1/10 inch in the rain gauge is actually 1 inch of rain. It can measure as little as .01 inches of rain.

What do meteorologists use to collect rainfall?
they use a rain gauge and measure the rainfall

Why can't you place a rain gauge near a building?
You can place it on the roof, but not on the sides. Blowing wind can create a "rain shadow" on one side, with drops blocked as they fall. Alternately, projections from the building could funnel rain from a large wall area into the gauge.

Description of rain gauge?
A funnel closed at the bottom. made of glass or some transparent plastic. the spout part is long and graduated in inches.
What is the technology that shows the form amount and location of precipitation?
It is an ancient weather instrument called a rain gauge. A funnel is inserted into a tube. A measurement of 1/10 inch in the rain gauge is actually 1 inch of rain. It can measure as little as .01 inches of rain.
How does a rain gauge work rain gauge?
a rain gauge works by first making sure it rained, and seeing how many inches the rain filled up the rain gauge.
Does a rain gauge measure the amount of rain?
Yes, a rain gauge measures the amount of rain to fall above the gauge.
Why does one inch in an offical rain gauge actually measure only one tenth of an inch of rain?
Because area of the opening of the collector is ten times the area of the measuring tube (it is a funnel). This provides for more accurate measurement of small amounts of rain.
What is the use of a rain guage?
The Rain Gauge is used to measure the rainfall or Precipatation
