FIELD: measuring technology.
SUBSTANCE: invention can be used to measure the wear of smoothbore or rifled barrels. The barrel wear meter contains a measuring cylinder with known geometric dimensions placed inside the barrel, to create excess pressure in the breech section - an oil tank, a pipeline for supplying oil to the breech, a main valve. The barrel bore wear gauge is installed vertically and additionally contains: a flow meter, a float with an axial rod protruding from it, graduated in units of length and containing a reading index to determine the vertical position of the free oil surface during measurements.
EFFECT: possibility to simplify measurements and improve accuracy.
