This invention allows measuring the density of clear oil products, spirits, and other liquids in laboratory conditions and outdoors with a density measurement accuracy of +- 0.05 / 0.1 per cent within the temperature range of -50 / + 50 degrees C. The densitometer is composed of a cork, a coaxial tube, a cork retainer, and a ferromagnetic iron, which is subsequently placed into the induction-coil, spring-type counteraction unit, and thermometer and autonomous power supply measuring unit. It is recommended to split the densitometer (Fig.1) tube into two: flow tube, which has its end in the support base, and another tube with a ferromagnetic iron in it, which is placed inside the induction-coil and fixed with placoid springs attached to the cases. In addition, the position adjustors for the iron and calibrating counterbalance units are placed at the ends of the tube.<IMAGE>
