Abstract: The problem with the known “sublayer fence” skin friction sensor is the disturbance caused by the fence protruding above the surface. Author comes with the solution preventing the premature transition into turbulence or even flow separation. In his original version of thesensor the fence is submerged slightly below the surface. Detailed investigations revealed the pressure difference output to be dependent on creation of two recirculation regions. An attempt tofacilitate the recirculation, quite surprisingly, has led to the merging of the vortices and total disappearance of a useful output signal.
