Abstract
This paper deals with how to correct the indication of the float-area type flow meter when line pressure changes. Float-area type flow meters are often used for small range flow rate measurements. In this range of measurement, flow rate characteristics of the meter are affected by the pressure drop in the small annular slit between float and tube. According to the analysis, new correction method for float-area type flow mether is introduced. The experimental data are in satisfactory agreement with the calculated results of the flow meter.
