technological processes of production of liquids, determination of brand of automobile fuel, in particular. SUBSTANCE: device has vessel with inlet hole which is divided by vertical partitions into communicating spaces possessing upper and lower rests. Each space houses floats with different calibrated values of volumetric density which form scale of allowance test of density of tested liquid. Indicator is vertical partition between adjacent, sunk and floating, floats. Difference of volumetric densities of two adjacent floats is equal to allowance zone of tested liquid. Device also has thermometer and its front panel is made of clear material. EFFECT: increased productivity of operation of allowance test of density of liquids, enhanced sensitivity of device. 1 cl, 1 dwg
