Способ градуировки и поверки расходомеров газа, основанный на пропускании газа через расходомер, измерении времени пропускания и изменения давления в калиброванной емкости при постоянной температуре и определении расхода с помощью измеренных величин, отличающийся тем, что газ, прошедший через расходомер, напускают в емкость и при этом поддерживают сверхкритический перепад давлений между расходомером и емкостью.A method for calibrating and calibrating gas flow meters, based on passing gas through a flow meter, measuring the transmission time and pressure changes in a calibrated tank at a constant temperature and determining the flow rate using measured values, characterized in that the gas passing through the flow meter is let into the tank and maintain a supercritical pressure differential between the flowmeter and the tank.
