The sensitive element of an instrument for sensing small deviations in concentration, in which a temperature correction is automatically introduced, consists of a hydrometer and a thermometer in one unit (the hydrometer tube is filled with mercury or alcohol). The parameters of the sensitive element are such that the linear values of the hydrometer immersion depth and the height to which the liquid rises in the tube are equal over a wide range of temperatures. The radioactive isotope floats on the surface of the thermometric liquid, and its radiations are received by pulse counters connected to an electronic unit. The output from the electronic unit is connected to the concentration indicator and a signal device. The measurement system may be of relay or proportional type, depending on the number of counters and the way in which they are installed. An overflow is used to ensure that the liquid being measured is at a constant level. Formulas are given for calculating the volume and weight of the thermometric liquid.
