Abstract
The aim of this paper is to show how to analyze and correctly choose a measuring device especially applied to the mass flow meter based on the Coriolis principle. In the beginning, a short description of a Coriolis based mass flow meter is given. Furthermore, comparison analysis of two flow meters indicates the problems of a method wrongly applied to slurry fluid measurement in production of a detergent powder plant. Analysis is made by using the RS Logix 500 software. The diagrams showing causes of
wrong measurements and position of the mass flow device determine a few malfunctions. Finally, comparison of measurement by a new mass flow meter shows that the measurement method is applicable to slurry fluids which are especially problematic and complex for measuring.
