The effect of temperature distribution inside the fluid level adapter on the temperature calibration

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.
