    Rheometric evidence of the apparent wall slip (AWS) effect is the main subject of this paper. It is necessary, to treat together primary viscometric data from viscometric configurations with different hydraulic radii (e.g. different gap thickness h). The simultaneous using of several configurations is the feature which distinguishes a classical viscometry from the AWS viscometry. Three various sensors for the AWS rotational viscometry are considered here. Two conventional sensors – coaxial cylinders (ZZ) and parallel plates (PP) – are compared with a novel sensor, the coaxial Morse-cone (KK), which seems to be most suitable for the viscometry under AWS effect. The related viscometric theory, based on two material functions – for fluidity and slip - is implemented to the PC software AWSWork, which supports the joint treating of primary viscometric data from different sensors.
