Level of measurement or scale of measure is a classification that describes the nature of information within the numbers assigned to variables.araphrasing N.R. Campbell (Final Report, p.340), we may say that measurement, in the broadest sense, is defined as the assignment of numerals to objects and events according to rules (Stevens, 1946, p.677).
Broadly, there are two types of level measurement, continuous level measurement and point level measurement. In continuous level measurement, the actual level of the media is known at all times from a level transmitter or transducer. Level transmitters most often provide an output of a linear 4 to 20 mA signal proportional to the media height.
