摘要：
There is provided a circulating line branched from a solution or suspension tank and returning again to this tank through a pump (15) used to control the flow velocity at a constant level. A fluid temperature is measured by a sensor (16) in said tank or said circulating line (14) while a temperature of a heating sensor (17) employing so-called electrically heating method and placed in said circulating line is measured. Concentration of a given subject in solution or suspension is determined based on a temperature of the heating sensor or a difference between a temperature of the heating sensor and a temperature of the fluid.
