A pressure measurement error using wall tap in a flow nozzle is examined in high Reynolds number. The pressure measurement error is estimated using measurement result of a discharge coefficient of the flow nozzle. The behavior of the differential pressure measurement error is clearly influenced by the tap diameter and the viscosity of the working fluid. To obtain the universal relation, several plots between the pressure measurement error normalized by wall shear stress and tap Reynolds number are presented. Finally, the best relation to universalize of the pressure measurement error is newly proposed in this paper.
