Concepts of Process Instrument Calibration

Measuring devices are an integral part of our lives nowadays, whether in everyday life or on the job. Take, for example, the scales at the supermarket check-out, the fuel volume measurement at the filling station pump, temperature measurement, velocity, flow volume and thermal energy, taxi meters etc. The wide variety of available quantities to be measured and measuring devices clearly illustrates the complex interplay between the quantity to be measured and the measuring device used. What does "accurate" actually mean in this context and how is this accuracy demonstrated? Why do we need accurate measuring devices?

Using the example of flowmeters, the following document will go into detail about these and other aspects of calibration and accuracy, and also looks at calibration standards from different countries around the world.
