The Levels of Measurement in Statistics - ThoughtCo

The fourth and highest level of measurement is the ratio level. Data at the ratio level possess all of the features of the interval level, in addition to a zero value. Due to the presence of a zero, it now makes sense to compare the ratios of measurements. Phrases such as "four times" and "twice" are meaningful at the ratio level.

Level of measurement - Wikipedia

Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio. This framework of distinguishing levels of measurement originated in psychology and is widely ...

Level Measurement - Omega Engineering

Radar Level Transmitters In applications requiring non-contact measurement of liquid levels, the affordable LVRD500 radar transmitter is the logical extension of ultrasonic sensors. They are ideal where vapor, dust, or a foaming surface prevents ultrasonic measurement. Their radar sensor uses microwave pulse technology to track target liquids from the antenna tip to the bottom of a tank.

About Guided Wave Radar | Emerson NL

Variations in level measurement can easily occur under these conditions, but the guided wave radar technology is unaffected by these changes. The device does not need to compensate for changes in density, dielectric, or conductivity in the fluid and this makes this top down measurement very robust.

How Do We Measure Sea Level? | NASA Climate Kids

18-6-2020· Finding an average of all those measurements gives an average sea level for the whole planet. During the next 10 days, Jason-3 does it all over again – and again and again, year after year! By seeing how the average distance from the top of the ocean to the center of the Earth increases over time, we can measure how much and how quickly sea level is rising.

The same is true with radar level measurements. A low frequency radar—such as 6 GHz with a longer wavelength—is better able to penetrate dust and steam than 80 GHz with its short wavelength. Determining which frequency, wavelength and beam angle to use depends on conditions in the silo, as discussed below.

Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as well as bulk solids. They are also widely used in water treatment applications for pump control and open channel flow measurement. The sensors emit high frequency (20 kHz to 200 kHz) acoustic waves that are reflected back to and detected by the emitting transducer.

IFRS 13 — Fair Value Measurement

IFRS 13 applies to IFRSs that require or permit fair value measurements or disclosures and provides a single IFRS framework for measuring fair value and requires disclosures about fair value measurement. The Standard defines fair value on the basis of an 'exit price' notion and uses a 'fair value hierarchy', which results in a market-based, rather than entity-specific, measurement.
