FAQs On Rain Gauges

Who needs a rain gauge? Why is this instrument used? There are a couple of questions that linger in your mind and that one is sure. If you want the answers to your queries, then, here are some vital frequently asked questions that will definitely satiate you.

Who often uses the rain gauge?

For formal purposes, the meteorologists and hydrologists use the rain gauges to determine the amount of rainfall for a certain period of time in a given area. The unit of measurement used is either inches or millimeters. A weather station interprets the data and keeps the records. In some cases, the reading of the data can be done manually. The characteristic of the rain as to whether it is light, medium, or heavy is likewise determined.

What generally comprises the modern tipping bucket rain gauge instruments?

The modern style of tipping buckets is typically composed of the plastic collector which is balanced over a pivot. It is able to activate the reed switch whenever it tips. Thus, it electronically transmits the recorded data to the remote weather collection station.

These kinds of tipping gauges are also able to feature the weighing gauges. Meaning, a sort of strain gauge is connected to the collection bucket which allows the reading of the precise rainfall at any given time. Every time that the collector tips, the strain gauge or that which is otherwise known as the weight sensor prompts re-zeroing to rule out any confusion in the readings.

How can frozen precipitation be measured?

In cases of heavy snow, what is sure to happen is for the rain to get frozen. To be able to gauge the frozen precipitation's water equivalent, the tipping bucket may actually be heated. This allows the melting of the ice and snow which have been caught in the instrument's funnel.

What happens when the tipping bucket isn't heated?

In the absence of any effort to heat the bucket, the funnel gets clogged up. This normally happens during the fusion of the heavy rains and severe snow. If there is no heating mechanism, then, the precipitation can't be measured.

Can the rain gauge measure snow?

If it frequently snows in your area, it is safe to note that many of the rainfall measuring devices will not successfully apportion the snow fall. Generally, the snow will clog the opening of the instrument's collection funnel. If such is the case, then, you may opt to use the specially crafted snow gauges. They are already available in the market.

What is the optical rain gauge?

This instrument features a collection of funnels which are arranged in a row. The laser diodes as well as the photo transistor detector are placed inside a closed space. As soon as there is enough water collected, then, a single drop is made which is enough to drip from the bottom that falls towards the laser beam path. The sensors are placed at right angles following the laser so that an adequate amount of light is going to be scattered. The light that is emitted by the photo detectors are read, interpreted, transmitted, and finally, recorded.

Sure enough, you already know how the rain gauge works, what it is composed of, and what the designs are. One more thing, not only the professionals use it. You can make one for your own use!
