Uncertainty budget of pressure balance effective area determined by comparison method

This paper presents a simplified model for the evaluation of the measurement uncertainty of pressure balance effective area calibrated by method of comparison which is being applied at Laboratory for Process Measurements (LPM). The methodology is applied for oil-operated industrial pressure balances in the gauge pressure range up to 60 MPa. The scope of the procedure is illustrated by calculation example.
