温度修正对加油机计量检定误差的影响

Impacts of temperature modification on cali-bration error of greasers.

根据加油机检定规程(JJG443-98)的规定,介绍了加油机计量检定的容积比较法,并用实例怍了说明,指出若不对实际容量进行温度修正,就得不出准确的相对误差,即检定结果不能反映真实情况,强调只有严格执行国家检定规程,才能真正达到"计量准确,诚信经营"。

Volume comparison is used to calibrate greasers by comparing show value of greaser with actual output volume measured by standard gauge and getting relative error. It is illustrated that ac-curacy of calibration will decrease greatly unless error is modified by temperature.
