Two Model Functions for Calibration of Automatic Gravimetric Filling Instruments
M. Grum, G. Grgic
Abstract:
The article discusses basics of procedure for the calibration of automatic gravimetric filling instruments. It deals with the definition of the model function of measurement procedure, determination of the reference mass of test fills and estimation of measurement uncertainty. Depending on whether the calibrated instrument is able or not to record its results and on this basis adjust the filling process, two options for the selection of the calibration model function are addressed. Contributions to the measurement uncertainty are presented with an emphasis on the differences arising from the application of one or another model function.
