The change in the apparatus constant for vibrating densimeter made of glass tube observed under the ambient temperature change has been proved to be attributed to the following two main factors, one is the temperature dependence related with its dimension and elastic property, and the other is the change in the equivalent mass of the vibrator. The effect of these two factors has been studied by the theoretical and experimental analyses. Two kinds of glass tubes, one made of ordinary glass and the other made of fused quartz, have been used in this experiment. Experimental results show that the temperature dependence of the apparatus constant for the ordinary glass tube is larger than that for the fused quartz one. This phenomenon has been explained by the difference in the linear expansion coefflcient between them.
