Calibration in the measuring technology industry
Measuring devices are an integral part of our lives nowadays, whether in everyday life or on the job. They are often only recognised, however, when we take a much closer look. 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 sections will go into detail about these and other aspects.
This website gives an overview about the following topics:
- General principles and definitions
- Calibration of flowmeters, level transmitters and temperature transmitters
- Influences in practical use
- References and measurement standards
“Is this device calibrated?”, is a typical question heard relatively early on when using measuring devices. To answer this question in a satisfactory manner, different aspects of calibration are explained here.
Influences in practical use
When you consider the calibration values of a flowmeter, ideally they should not deviate from the measuring values in the application.
References and measurement standards
Calibration usually takes place with the help of a “more accurate” measuring device. This device is referred to as the reference, the measurement standard or superior measurement standard.
