Ability of circular shaped sublayer plate has been examined for simultaneous measurement of magnitude and orientation of the local wall shear stress. Improvement of angular resolution was proposed with multiple 6 pressure taps around the circular shaped sublayer plate. A single calibration curve successful represents relation of the wall shear stress and pressure difference for 2.4<h+<14.9 and D=10[mm]. If the plate is submerged in the linear sublayer, detection sensitivity of the sublayer plate is slightly larger than Razor blade method. Defining ratio of static pressure of the multiple pressure taps, the angular resolution can be improved around 0 degree in attack angle of wall flow.
