This paper presents a technique of liquid temperature measurement using estimators. The objective of the proposed work is to design an estimator for measuring the liquid temperature in a process tank by analyzing the behavior of available capacitive level sensor (CLS). Input output characteristics of the capacitive level sensor is analyzed for variation in liquid level and temperature. An observer is designed using the principle of regression analysis to compute the relation between the capacitive level sensor outputs for variations in liquid temperature. Kriging estimator are used as observer to compute the unknown liquid level and temperature from the output of capacitance level sensor. The designed temperature measurement technique is validated by performing the experiment in simulation and on practical setup. Results obtained by the technique shows successful implementation of proposed estimator
