What Is a Rain Gauge?

A rain gauge is an instrument used to measure the amount of liquid precipitation over a unit area. It is a useful tool used by hydrologists and meteorologists to gauge precipitation levels over time. A rain gauge measures the depth of precipitation in a unit area. A rain gauge is a type of trough placed in a drainage ditch, and the water level in the trough will be used to determine the amount of rainfall in the area.

Most rain gauges are made of plastic and are positioned directly into the ground. Digital rain gauges are more sensitive and can send data to your phone via an app. For example, a tilting bucket rain gauge is linked to a logger that records the event in computer compatible form. This type of trough empties once it collects five millimetres of rain. The trough is typically a small plant pot. If you want a gauge that measures rainfall, choose a model that has an overflow mechanism. This feature will allow you to measure rainfall down to one-hundredth of an inch.

Another type of self-recording rain gauge uses a pair of graduated cylinders. One cylinder is the receiver bucket, and the other is a larger graduated cylinder. The inner cylinder measures the height of the rainwater, and the second weighing cylindric is the total rainfall measured. The two cylindrical structures are connected by a spring, and the outer cylinder supports a pair of buckets.

Depending on the model, the rain gauge can be a digital or analog one. The former is the most common type and uses an electro-mechanical sensor to measure the amount of precipitation. This type of rain gauge is more accurate and reliable but may be subject to errors due to wind and uneven terrain. Therefore, if you plan to install a rain gauge, ensure you place it in a well-lit area and use it regularly.

A rain gauge is an instrument used to measure the amount of rainfall in a given area. This type of instrument allows you to see how much rainfall has fallen in a given area over time. By placing the gauge near the gutter, you can observe how the rainfall level changes over time. A standard rain gauge should be placed at least four to five feet above the ground and away from obstructions. If you plan on installing a rain gauge in your home, make sure the location is free of obstacles and obstructed by trees and other objects.

Besides determining the precipitation depth in a unit area, a rain gauge also monitors rainfall intensity. In countries with a high snow cover, regular surveys of snow courses are required to measure rainfall accurately. A rain gauge can be buried in deep snow, but it will still give good readings if you use a standard model. If you don’t have a rain gauge, you can purchase a wireless one for your home
