How Does a Rain Gauge Work?

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.

How Does a Rain Gauge Work?

A rain gauge is an instrument used to measure the amount of precipitation that falls from the sky. It is a simple device composed of a tube, a funnel and a measuring container. Rain gauges are typically used in meteorological observations to help determine the amount of rain or snow that has fallen during a specific period of time. This data is then used to help predict the weather and forecast future weather patterns.

The rain gauge works by collecting the water that falls from the sky and funneling it into a measuring container. The container will usually measure between 0.2 and 0.3 inches of rainfall. The water is then collected and measured in millimeters or inches, depending on the type of rain gauge being used. The rain gauge is then reset back to zero when the container is full.

The size of the measuring container on the rain gauge will depend on the type of precipitation being measured. For example, if it is measuring snow, the container will need to be larger than if it is measuring rain. The rain gauge is also calibrated to measure the amount of rain that has fallen. This is done by setting the rain gauge to the appropriate level for the type of precipitation being measured.
