Abstract
Способ калибровки и поверки газовых счетчиков, при котором размещают эталонные счетчики в трубопроводном тракте, отличающийся тем, что калибровку и поверку газовых счетчиков проводят в замкнутом цикле на реальном газе и при реальном давлении, а при подаче воздуха в трубопроводном тракте создают поток газа или воздуха, при этом поток воздуха регулируют путем изменения частоты вращения турбины, величину расхода контролируют эталонным счетчиком, при этом в течение заданного интервала времени подсчитывают количество импульсов, формируемых поверяемым и эталонным счетчиком, и путем умножения на цену импульса, индивидуальную для счетчика, который поверяют и эталонного счетчика, вычисляют объем газа в рабочих условиях, при этом выполняют перерасчет объема воздуха в стандартных условиях, а погрешность при поверке счетчиков вычисляют путем сравнения объемов воздуха в стандартных условиях, поверяемых и эталонных счетчиков.A method of calibration and calibration of gas meters, in which reference meters are placed in the pipeline path, characterized in that the calibration and calibration of gas meters is carried out in a closed cycle on real gas and at real pressure, and when air is supplied in the pipeline path, a stream of gas or air is created, while the air flow is controlled by changing the speed of the turbine, the flow rate is controlled by a reference counter, while the number of pulses is counted over a specified time interval, generated x the verified and reference counter, and by multiplying by the price of the pulse, individual for the counter, which is verified and the reference counter, calculate the gas volume under operating conditions, while recalculating the air volume under standard conditions, and the error in checking the meters is calculated by comparing the air volumes in standard conditions, verifiable and reference meters.
