Characterization of LPM diving-bell manometer

This paper presents characterization of diving-bell manometer in the gauge pressure range from -1.0 up to 3.0 kPa in the Croatian national pressure laboratory - Laboratory for Process measurement (LPM), located at the Faculty of Mechanical Engineering and Naval Architecture (FSB), University of Zagreb. The work points out comparison of two independent methods for diving-bell effective area determination i.e. determination based on dimensional measurements as well as determination of the effective area by a pressure comparison method. The dimensional measurements were performed in the Croatian national length laboratory, also at FSB. Determination of the effective area by the pressure comparison method was performed in LPM using a Physikalisch-Technische Bundesanstalt (PTB) Rosemount pressure transducer previously calibrated in PTB Braunschweig. From the results it can be seen that the difference in the effective areas obtained with the two independent methods is very small compared to the estimated effective area measurement uncertainties.
