Metrology

Metrology encompasses all measures for determining the status of physical quantities and leverages measuring instruments and methods for quantifying (measuring) physical quantities such as length, weight, force, pressure, current, temperature, and time.

Heightened technical and economic requirements for developing, manufacturing, and operating centrifugal pumps make it increasingly necessary to quantify physical states and quantities, thus enhancing the scope of measurement tasks. This also applies to measuring instruments as used for monitoring and closed-loop control purposes, whereby conventional measuring tasks are carried out via improved methods as new methods are added.

Electric and electronic measurement methods are increasingly being used and have already established themselves as irreplaceable in many areas.

Current technical developments are characterised by their application of electric (digital) measured value transmission for multi-value measuring equipment and data-processing facilities.

Important sub-areas of metrology are the development of measuring systems and measurement methods and the processes of recording, modelling, and reducing (correcting) measurement errors and undesired influences. This also includes the adjustment and calibration of measuring instruments. Metrology is required for automation in conjunction with open-loop and closed-loop control systems.
