体积管在每次检定前,都需要清洗,清除内部原油及管壁结蜡。清洗达到可检定条件后,再利用标准金属量器对其标准容积值进行检定。在整个过程中,清洗方法、清洗效果、相关设备、水质及水温、检定过程中的操作等各个环节都会对体积管检定的准确性造成影响。如果处理不当,势必影响交接双方的经济利益,造成不必要的计量纠纷。
The volumetric tube needs to be cleaned before each calibration to remove internal crude oil and wall waxing. After the cleaning reaches the verifiable condition, the standard volume value is checked by the standard metal gauge again. Throughout the process, cleaning methods, cleaning effects, related equipment, water quality and water temperature, the verification process and other aspects of the operation will have an impact on the accuracy of the volume tube test. If handled improperly, it is bound to affect the economic interests of both parties involved, resulting in unnecessary measurement disputes.
