A rain gauge (also known as an udometer, pluviometer, or an ombrometer, or a cup) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined period of time.

The meters, which tell you if the soil is wet, moist, or dry at the root level, are especially effective for large potted plants. Other soil moisture monitoring tools, often used for agricultural applications, include tensiometers and electrical resistance blocks, which indicate the moisture tension of the soil.

Sensing rain Ants are equipped with a full array of senses that could, in theory, give them clues about imminent rainfall. ... Ant antennae can also detect tiny changes in temperature, which might allow them to sense and react to the drop in temperature that usually accompanies a rain storm.

Rain: Precipitation in the form of liquid water drops that have diameters greater than 0.5 millimeter; if less than 0.5 millimeter, it is drizzle. ... Drizzle is classified as light, falling at a rate from a trace to 0.01 inch per hour; moderate, 0.01 to 0.02 inch per hour; heavy, greater than 0.02 inch per hour.

A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.

A disdrometer is an instrument used to measure the drop size distribution and velocity of falling hydrometeors. Some disdrometers can distinguish between rain, graupel, and hail. The uses for disdrometers are numerous.

cm, say, collects 1 cm height water. When poured in a measuring glass cylinder with 10 Sq Cm base, the height will be amplified to 10 Cm but graduation will show as 1 cm; 1 cm will be 1 mm;and 0.1 cm will be 0.1 mm. So rainfall can be measured correct up to 0.1 mm. 9.5K views. View 4 Upvoters.

A variety of instruments can be used to measure wind direction, such as the windsock and wind vane. Both of these instruments work by moving to minimize air resistance. The way a weather vane is pointed by prevailing winds indicates the direction from which the wind is blowing.

A refractometer is the instrument used to measure refractive index ("RI"). Although refractometers are best known for measuring liquids, they are also used to measure gases and solids; such as glass and gemstones.

A Casagrande device is the primary laboratory tool for testing liquid limits. The tester places soil samples with varying water contents into the cup of the device, then cuts a groove through the sample. The cup is dropped multiple times until soil fills the groove.
