FIELD: metrology. SUBSTANCE: piston pumps fluid through a flow meter to be checked. The piston moves with acceleration along the calibrated part of the pipe line. Variation of cross- section areas along the calibrated pipe line part is defined preliminary. Speed of the piston changes reversely proportional to changing of areas of flowing sections of the pipe line in the direction of pump moving. EFFECT: simplified method. 1 dwg
