There are two types of rain gauges, non-recording type and recording type. Rain gauge is a type of instrument used by meteorologists and hydrologists to measure rainfall rate in a certain period of time. Rain gauges are also known as udometer, pluviometer and ombrometer.
What are the types of rain gauge?
The three major types of rain gauges are the standard gauge, tipping bucket gauge and weighing gauge. Further distinguishing aspects such as how they are set up and how they deliver data can be made, though the basic operation of rain gauges does not usually vary from these primary rain gauge types.
What are the three types of recording gauges?
Three types of recording rainfall gauges are in general use, i.e. weighing type, tipping bucket type and float with siphon type.
What is a rain gauge also called?
A rain gauge (also known as an udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined area, period of time.
What is float type rain gauge?
A class of rain gauge in which the level of the collected rainwater is measured by the position of a float resting on the surface of the water. This instrument is frequently used as a recording rain gauge by connecting the float through a linkage to a pen that records on a clock-driven chart.
What is rain guage used for?
OBJECTIVE: Make and use a rain gauge, an instrument used to collect and measure precipitation (falling water). It measures the depth of the water that would cover the ground if the rain did not drain away or evaporate.
How is rain measured in a rain gauge?
A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It’s that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.
Which is the most common type of rain gauge?
1. Non-Recording Type Rain Gauge. Non-recording type rain gauge is most common type of rain gauge used by meteorological department. It consists of a cylindrical vessel 127mm in diameter with a base enlarged to 210mm diameter.
Is code for rain gauge?
6.5 Raingauge of appropriate capacity as specified in IS 5225 shall be used to ensure the measurement of extremes of rainfall in the event of the observer being unable to take observations repeatedly on the day of such heavy rainfall.
What is difference between non-recording and rain gauge?
1. Non-Recording Type Rain-Gauge: It gives only total rainfall occurred during particular time period. Recording type rain- gauge gives hourly rainfall.
What is rain gauge class 9?
A rain Gauge is an instrument used by the meteorologists and hydrologists in order to gather and calculate the quantity of liquid precipitation over a recorded period of time. Record the result and then study the findings.
How do I choose a rain gauge?
The height of a rain gauge typically ranges from 5 to 20 inches, while the diameter of its cylinder ranges from 2 to 8 inches. It’s quite simple: the larger the cylinder, the more rain collected and the more accurate the readings are. If you live in an area where it rains a lot, a larger rain gauge is a wise choice.
What is a simple rain gauge?
Rain gauge is a meteorological instrument for determining the depth of precipitation (usually in mm) that occurs over a unit area (usually one metre square) and thus measuring rainfall amount. One millimetre of measured precipitation is the equivalent to one litre of rainfall per metre square.
