Abstract: The title of tills paper, Recording and Controlling Instruments, contains only two of the six words which constitute the theme song of the Industrial Instrument business. The six vital words are Indicating, Recording, Controlling, Pressure, Temperature, Time. These words, which name the three principal varieties of instruments and the three fundamental variables with which these instruments are concerned, are not the entire song they are just the refrain. There are a lot of verses concerned with other variables with combinations of variables, and with combinations of instrument functions. Some of these other variables such as, rate of flow, liquid level, absolute pressure and vacuum are special cases of pressure. In addition, there is a long list of variables which are quite distinct from the three basic ones. .Although these others are outside the scope of this paper, they deserve mention because of the insight that they give into the possibilities of industrial instrumentation. A list of these variables reads a little like the table of contents of a physics text-boob. Light, sound, electricity weight, velocity, acceleration dimensions, density, viscosity humidity, chemical composition, stress and strain. These and more, but of greater interest than a complete list are some applications which may be chosen from those just named.
