первом измерении, одновременно снимают показани  счетчиков 1 и 3. Как известно, счетчики (например, турбинные ) при Стабильных услови х имеют очень высокую повтор емость показаний (0,01-0,2%) что позвол ет использовать их дл  фиксирова ни  количества пропущенной жидкости или газа через повер емый счетчик и обеспечени  необходимой точности поверки. При зтом сче чик, фиксирующий количество пропущенной жидкости или газа, не требуют градуировки, важна только его высока  повтор емость, чтобы при первом и втором измерени х он фиксировал одинаковое количество жидкости или газа. Далее определ ют разность показаний повер емого счетчика 1 при первом и втором измерени  и сличают ее с показание образцового счетчика 3, в чем и заключаетс  процесс поверки. Погрбишость счетчика определ ют по формуле: л где V о показание образцового счетчика; V, разность показаний повер емого счетчика при первом и втором измерени х. Формула изобретени  Способ градуировки и поверки счетчиков жидкости или газа путем сравнени  их показаний с показател ми образцового счетчика, отличающийс  тем, что, с целью снижени  затрат на поверку, сначала пропускают через последовательно установлениые два повер емых счетчика одинакового предепа фиксированное количество жидкости или газа, измер ют разность их показаний, затем то же количество жидкости или газа пропускают через параллельно установленные повер емый счетчик и образцовый счетчик меньше предела, определ ют разность показаний повер емого счетчика при первом и втором измерении и сравнивают ее с показани ми образцового счетчика.the first measurement, simultaneously read the readings of the meters 1 and 3. As is known, the meters (for example, turbine meters) under Stable conditions have a very high repeatability of readings (0.01-0.2%) which allows them to be used to record the amount of missed liquid or gas through a calibrated meter and ensuring the required accuracy of calibration. In this case, the counter that fixes the amount of the missed liquid or gas does not require calibration, only its repeatability is important, so that during the first and second measurements it fixes the same amount of liquid or gas. Next, the difference between the readings of the calibrated counter 1 at the first and second measurements is determined and compared with the indication of the reference counter 3, which is the verification process. The meter count is determined by the formula: l where V is the reference meter reading; V, the difference between the readings of the calibrated counter during the first and second measurements. The invention The method of calibration and calibration of liquid or gas meters by comparing their readings with those of an exemplary meter, characterized in that, in order to reduce the cost of calibration, they first pass through two consecutively installed counters of the same degree with a fixed amount of liquid or gas measured the difference between their readings, then the same amount of liquid or gas is passed through a parallel-installed counter meter and an exemplary counter less than the limit; five readings power metal emogo counter when the first and second measurement and compared with the indications E exemplary counter.
