Abstract

The purpose of this work was to study the temperature distribution inside the fluid level adapter. This is the effect during thermometer calibration. The fluid level adapter is an accessory to lift the level of fluid inside the bath, for reducing the immersion errors. In this case, the maximum level that could be lift was about 5 cm from fluid reference level in the bath with the maximum flow rate 299 cm3/s. From the calibration results, it was found that the estimate uniformity and stability of measurement in the measuring zone are suitable to perform for thermometer which not over ±0.05oC accuracy require and some types of LIG thermometer calibration such as ASTM standard LIG thermometer model of 63C, 64C, 64C and 65C types, wherewith the range from -8oC to 105oC thermometer.

液位适配器内部温度分布对温度校准的影响

本工作的目的是研究液位适配器内部的温度分布。这是温度计校准时的效果。液位适配器是一种配件，用于提升槽内流体的液位，以减少浸入误差。在这种情况下，在最大流速299 cm3/s的情况下，可以提升的最大水位线距离槽内流体参考水位线约5厘米。校准结果表明，测量区的测量均匀性和稳定性可适用于精度要求不超过±0.05℃的温度计和某些类型的LIG温度计的校准，如ASTM标准LIG温度计型号为63C、64C、64C和65C，范围为-8℃至105℃的温度计。

期刊介绍： Publication of the journal started in 1974. Its original name was “KKU Engineering Journal”. English and Thai manuscripts were accepted. The journal was originally aimed at publishing research that was conducted and implemented in the northeast of Thailand. It is regarded a national journal and has been indexed in the Thai-journal Citation Index (TCI) database since 2004. The journal now accepts only English language manuscripts and became open-access in 2015 to attract more international readers. It was renamed Engineering and Applied Science Research in 2017. The editorial team agreed to publish more international papers, therefore, the new journal title is more appropriate. The journal focuses on research in the field of engineering that not only presents highly original ideas and advanced technology, but also are practical applications of appropriate technology.
