The problem with existing principles of skin friction measurements are the disturbances caused by the components of the sensor protruding above the surface, however small they are. Also the hot film versions were demonstrated to change the character of the flow. Author has eliminated these adverse influences in his original version of the sensor with the fence submerged slightly below the surface. Recent detailed investigations revealed the pressure difference output to be dependent on creation of miniature recirculation regions. An attempt to facilitate the recirculation, quite surprisingly, has led to total disappearance of a useful output signal.
