在高压大流量气体计量技术上,由于长期以来缺乏标准试验设备,为此量值很难正确传递与统一,所以无法正确开展气体计量。这给供气单位与用气单位正确计算用气量,以及正确经济核算带来莫大困难。虽然上海石油化工总厂气体计量仪表都是日本引进,但仪表在使用较长时间后,其量值是否仍然正确,必须进行重新标定。在乙烯气等气体计量上,供气单位与用气单位
In the high-pressure and high-flow gas measurement technology, due to the lack of standard test equipment for a long time, it is difficult to correctly transfer and unify the values so that gas metering can not be carried out correctly. This gives the gas supply units and gas units to correctly calculate the amount of gas, as well as the correct economic accounting bring great difficulties. Although Shanghai Petrochemical General Factory gas meters are imported from Japan, but the instrument in use for a long time, its value is still correct, you must re-calibration. In ethylene gas measurement, gas supply units and gas units
