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.
Levels of measurement. What a scale actually means and what we can do with it depends on what its numbers represent. Numbers can be grouped into 4 types or levels: nominal, ordinal, interval, and ratio. Nominal is the most simple, and ratio the most sophisticated. Each level possesses the characteristics of the preceding level, plus an additional quality. Nominal. Nominal is hardly measurement. It refers to quality more than quantity. A nominal level of measurement is simply a matter of distinguishing by name, e.g., 1 = male, 2 = female. Even though we are using the numbers 1 and 2, they do not denote quantity.
