Rain gauges are designed to measure the amount of precipitation in a location, usually in mm or inches. Rainfall is one of the primary factors used to determine whether a place is humid or arid. The significance of rain gauges stems from their ability to measure the exact volume of rain that has fallen at any given time.
There are several different types of rain gauges, each with its own advantages and disadvantages. Understanding how they work can help you pick the best one for your needs.
This article will provide an overview of various types of rain gauges and how do rain gauges work, so you can decide which one would suit your situation and circumstances best.
What is a Rain Gauge?
A rain gauge is a device used to measure the amount of rainfall in a certain location. Rain gauges come in various designs, but they all work on the same principle: precipitation gets collected in a container, and the amount of water collected can be measured. It’s important to note that not all gauges are created equal.
Some are better for measuring rainfall than others, and the best one for you will depend on your specific needs and circumstances. Rain gauges come in two main types:
- Drainage rain gauges: These are designed to collect rainwater that falls on top of the gauge through a funnel that leads down to the container below.
- Condensation rain gauges: These gauges collect water from raindrops that condense on the gauge itself. There are other variations of rain gauges, but these are the most common and are suitable for different applications and environments.
Drainage Rain Gauge
A drainage rain gauge is used to measure the amount of water that falls on the gauge itself, rather than the surrounding area. A drainage gauge is typically a cone-shaped device made of metal, wood, or plastic that sits in the ground. The funnel at the bottom of the gauge is shaped so that rainwater is directed into a container below, where it can be measured.
A drainage rain gauge works best in places where you want to specifically measure the amount of water falling on a certain spot. This can be helpful in situations where a specific plant or object needs regular watering, or you want to measure the amount of water in a particular area.
Drainage gauges are also useful in places where there’s a risk the water might evaporate before it gets collected by other devices or methods.
Condensation Rain Gauge
A condensation gauge is used to measure the amount of water that is condensed and collected on the gauge itself. This can happen when air and water vapor mix together and form liquid water droplets. A typical condensation gauge is a cone-shaped device made of metal, wood, or plastic.
It’s placed in an area where it will be exposed to the open air, and water vapor from the atmosphere will condense on the gauge’s surface. A condensation gauge works best in humid environments and low-lying areas, where there’s a lot of moisture in the air. It can also be used under certain conditions in arid environments, where there isn’t much water vapor in the air.
Standard Rain Gauge
A standard rain gauge is used to measure the amount of water that falls in a particular area and gets collected in the gauge. A standard gauge is designed to collect rainwater from an open area in a way that’s representative of the total rainfall in the surrounding environment. This means that a standard rain gauge is less accurate than other gauges.
A standard rain gauge is often shaped like a cylinder, with a funnel at the top to catch and direct falling rainwater into a container below. As with other gauges, the container is used to measure the total amount of rain that has fallen in a certain area.
Electronic Rain Gauge
An electronic rain gauge is used to measure the amount of water that falls in a particular area and gets collected in the gauge. An electronic rain gauge is like a standard gauge in many ways, but it also features an electronic sensor that automatically records the amount of rainfall. This makes an electronic rain gauge more accurate than a standard one.
An electronic rain gauge is often shaped like a cylinder, with a funnel at the top to catch and direct falling rainwater into a container below. The electronic sensor works by measuring the amount of water that gets collected in the container, and it automatically records this data for later review.
Conclusion
Rain gauges are used to measure the amount of rainfall in a certain location. Rain gauges come in various designs, but their operation is similar: precipitation gets collected in a container, and the amount of water collected can be measured.
There are two main types of rain gauges: drainage and condensation. Drainage gauges are designed to collect rainwater that falls on the gauge itself, while condensation gauges collect water that condenses on the gauge’s surface.
A standard rain gauge is used to measure the amount of water that falls in a particular area and gets collected in the gauge. An electronic rain gauge also measures the amount of water that falls in a particular area, but it also automatically records this data.
