Abstract

Short description of borehole tool for measurement of temperature and conductance of liquid is given. Borehole tool is measuring these two parameters in same time. Conductance of liquids is important water quality parameter. Measurement of temperature is useful for normalization of conductivity readings and for locating at which depth liquids flows into the borehole. Principle applied is known as “four wire measurement” where maintaining of constant voltage on inner electrodes is accomplished by regulating of current through outer electrodes. Current flowing through liquid is proportional to its conductivity. Measurement of temperature is realized with platinum resistance thermometer PT100. In this paper description of the tool and mechanical realization of measurement elements are given.
