, it is necessary to which glass-stem thermometer exposes liquid level 1.5cm when the thermometer measures, otherwise need to be modified, measuring
Standard measuring device center can not equally be reached in journey, thermotonus speed is slow, proposes that liquid level is read when thermometer measure finishes
During number, due to the factors such as temperature change be present, so as to cause uncertainty of the temperature survey in real process.
（2）Quantitative refueling refuels to have fuel charger error with non-quantitation to be influenceed.Due to the presence of magnetic valve in fuel charger,
Fuel charger error in dipping receives closes valve amount and actual oiling V in advance1Influence, the valve amount V of pass in advance typically set1For constant, institute
To be had a great influence when refueling seldom to fuel charger error, in practical operation, quantitative refueling refuels with non-quantitation and examined and determine
Result is different, and only has regulation to the error of quantitative refueling in code at this stage, and non-quantitation refuels in real life
Error do not account for.Because standard metal vessel do not have suitable period check device within the re-testing periods, process is being used
In if tank body deforms, be not easy to find in time, can only wait after next re-testing periods serve the calibrating of grade metrological service
