Detector for round cross section sample wall surface fluid friction resistance

A frictional resistance measurement device of wall-surface fluid on round section test sample consists of model support unit including model head, front slide support ring, back slide support ring, model tail, fixing frame and support rod; and resistance measurement unit including transmission ring, radial transmission pin, axial transmission pin, transducer support sheath, transducer and transducer base. It is featured a setting measured test sample to be cylindrical form, placing transducer in runner and leading signal line out through hole.
