FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and can be used in machine building for active monitoring of diameters of cylindrical surfaces for example during testing of items with high pressures. Proposed device comprises support structure with level meter and measuring unit. Support structure is made in form of part of pipe, upper side of which has flat site for level meter installation. On lower side of support structure measuring unit is installed, which measures distance to pipe surface during tests along vertical diameter of pipe.
EFFECT: improving accuracy and enlarging technological capabilities of measuring cylindrical surfaces during tests under pressure.
