一、计量单位方面检定规程中都使用质量单位(kg),如最大流量、最小被测量、误差计算等,而实际中加气机上显示及结算的单位均为体积单位(m3)。误差计算可用密度值将质量和体积单位互换,但究竟是将加气机显示的体积值换成质量单位,还是将标准装置中的质量值换成体积单位,尚存争论。而最大流量、最小被测量、最小变量等如何判断,更无所适从。二、密度问题此问题与上一问题相关。因为使用单位不同,就
First, the unit of measurement Verification procedures are the use of mass units (kg), such as the maximum flow, the minimum being measured, the error is calculated, while the actual filling machine on the display and settlement units are volume units (m3). The error calculation can be used to interchange the mass and volume units with the density value, but it remains to be seen whether the volume value displayed by the dispenser is replaced by the mass unit or whether the mass value in the standard unit is replaced by the unit of volume. The maximum flow, the smallest being measured, the smallest variables, how to judge, more confused. Second, the density problem This question is related to the previous question. Because the use of different units, it
