The wet-surface profilometer (...) carries two recorder wheels (four for full-width construction of a two-lane carriageway) which are set in the same position relative to the chassis wheels as that occupied by the trailing edge of the vibrating beam (...). The recording wheels are counter-balanced so that the pressure on the concrete is only just sufficient to cause rotation, and the vertical movement of each is recorded autographically.  1, record 1, English, - recording%20wheel
