Introduction to Metrology and Measurements
Metrology is the science of pure measurement. The science of metrology had been applied to engineering to a limited extent before the first world war. However, considerable progress has been made in the application of scientific principles to the dimensional control of engineering products. In addition, accurate control of standards of Measurement was an important function of every precision engineering industry.
Metrology is concerned with the establishment, reproduction, conservation and transfer of units of measurements and their standards. It is also concerned with the methods, execution and estimation of accuracy of measurements, the measuring instruments and the inspectors. Dynamic metrology refers to a group of techniques for measuring small variations of a continuous nature. A legal metrology deals with the units of measurement, methods of measurement and the measuring instruments, in relation to the statutory technical and legal requirements.
