Top List On How To Measure And Use A Rain Gauge

Life without water would be like a day without night. Everyone needs water, and I can’t imagine a world without a good source of water. There are many sources of water these days, but the freshest of them is rain. People are dependent on rain for many reasons which include plant growth. A farmer lays his seeds down with the hope of getting rain and sunlight to help them grow. We sometimes pray for a downpour and most times for none. This is because we have our various use for rainwater.

Do you know that rainfall can be measured? What is the size of a rain gauge? If you’re one of those who need rainfall to go about your business and farming activities, you can measure the rain. Measurement helps you take the necessary precautions to determine your next move. To know the rain level for a particular period, you need a rainfall meter or a precipitation gauge.

There are different types of rain gauges that help you know the size of the rain. Meteorologists use rain gauges to measure rain. Getting excited about rain measurement can push you into buying a rain gauge before knowing without proper knowledge. Before purchasing a rain gauge, there are things to consider. People like gardeners or even aspiring people should go for the manual rain gauge. While farmers, agriculturists, and professional meteorologists should go for the automatic or direct rain gauge for appropriate reading.

How To Measure Rain With A Rain Gauge?

There are different types of rain gauge but the two major types are:

  • Recording rain gauges
  • Non-recording rain gauges

The non-recording rain gauges help collect the rain without recording the particular amount collect. While the recording rain gauges require calibration for accurate recording. Some of the recording rain gauges include measuring cylinder rain gauge, floating rain gauge, optical rain gauge, and tipping bucket rain gauge. Let’s go straight to explaining the measurement of rainfall.

How To Measure Rain With A Rain Gauge
  1. Measuring With A Non-Recording Rain Gauge

These types of rain gauges collect rain without accurate measurement. A Symons Rain Gauge is a perfect example of a non-recording rain gauge. It has a funnel, and metal bottle receiver that comes in a cylinder shape. The funnel fits the metal receiver neck, and there are packs attached to it. For efficient measurement, use a calibrated measuring jar.

This type of rain gauge can only measure rainfall for a given period. The funnel is the collector of the rain. You can raise it according to preference to avoid too many splashes. Acting as the measuring instrument is the graduated and not the gauge.

  1. Optical Rain Gauge

For a digital rain gauge, this is quite efficient. It uses optical detectors and lasers. Through the laser-optical detector gap where rain falls, you would notice the lightning level reduce. With an optical rain gauge, rainfall is measured by the difference in light.

  1. Measuring Cylinder Rain Gauge

It comprises a funnel and a large graduated measuring cylinder. The best part is that measuring cylinder rain gauge is the simplest so far. Place the funnel above the measuring cylinder to collect rain. You can measure rain directly as the water fills the jar. You can collect data without emptying water from the cylinder. Please do not compare this to a non-measuring cylinder because they serve a different purpose.

  1. Tipping Bucket Rain Gauge

A funnel has the job of collecting rainfall that will be directed to a cylinder and a bucket. The bucket will tip when water gets to a certain level, then you can bring in the next bucket. Since it is a digital rainfall meter or gauge, it works with a computer system. During rainfall, the computer gets signaled. The computer determines the amount of water obtained by the number of tips.

  1. Floating Rain Gauge

This rain gauge comes with a funnel that connects to the floating compartment. You would notice the float rise as water fills up the funnel. When the float rises, rainfall is traced and recorded to a rotating drum. A level system is present and it works with the pen. This is an easy measuring gauge to use.

There are defined rules, and principles to be followed before using a rain gauge. Indefinite or inaccurate results might pop up when if the rules are not followed.

  • Conventional Rain Gauge

Using a conventional rain gauge is quite easy. It collects rain in stores in a reservoir. The quantity of raindrops determines the rising level of the float, and a diagram interprets the intensity of water. When the tank gets full, a Siphon collects water. The water flows through to a container. A straight line follows immediately when the rain gauge is empty.



  • Other Models

This collects water with a meter and stores them in a tube. These models come with covers meant to stop the water from evaporating. Graduation uses precipitation gauges.

The only way you can know how to use a rain gauge is if you know how to interpret the result. When measuring rain gauge, be sure to follow the laid out rules. Some rain gauge requires strict follow up of the rules, which other don’t. If you experience any mistake, check the process or the gauge design. Be sure your environment is safe and in good condition for a rain gauge. Get an installer if you find it difficult installing the rain gauge yourself, this is to avoid incorrect data.

Conclusion On How To Measure And Use A Rain Gauge

Measuring rainfall can be thrilling if you know how to use it right. Rain gauges come in different forms and types, and they are all set to help you get the best result. People choose rain meters based on some factors such as speed, availability, efficiency, and effectiveness. They have a unique installation and usage process.
