quality control for
the whole process
If the quality criteria of VDI 2048 are not fulfilled, the causes need to be determined and corrected. In order to do this, the system supplies the user with indications about gross measurement errors (suspected tags) which then need to be newly calibrated. If the calibration does not indicate an erroneous measuring device, the estimated 95% confidence interval of the measurement needs to be increased.

The result is a description of the state of the process that is reflecting reality with the highest possible probability and at the same time with the smallest uncertainties. Currently used, highly precise measurement devices such as ultrasonic flow meters, tracer, etc. are singular pieces of information and cannot reach the quality controlled level of precision of PDR.
