In order to improve the measuring accuracy of plugging indicators, the relation be-tween the measured temperature and the impurity saturation temperature was investi-gated analytically for the oscillating plugging indicator. In the analysis, the differences between the true saturation temperature and the "plugging" or "unplugging" temperature were studied in view of the impurity precipitating mechanism.
By this investigation, the difference of measured temperature from the saturation temperature can be evaluated by a function of the dimensionless numbers Re and St and the suitable operating conditions on which the measurement error becomes small are ob-tained.
