Abstract: The proposed paper is focused on experimental viscometric study of AWS effect of aqueous polymer solutions: 1.5% wt solution of Na salt of Carboxymethylcellulose, 0.4%wt of Welan Gum and 1% wt of Polyacrylamide was chosen as the tested liquids. Four viscometric sensors (type KK) with different quality of surface (Stainless steel, Titanium, Alloy of Aluminum and Magnesium, as well as Stainless steel with surface roughened by sandblasting) have been used. It is documented that the extent of AWS effect strongly depends both on the sensor material and type of solution.
