Abstract

PURPOSE:To stably measure the density of a high temperature liquid extending over a long period, by detecting a pressure difference of a gas storage chamber of 2 pressure fetch ports provided on the side walls of a liquid tank, whose height is different, by a differential pressure detector formed by a pressure transfer liquid and a diaphragm. CONSTITUTION:2 pressure fetch ports 3, 4 are provided on positions which are separated from each other by a prescribed distance (h) and are different in height, on a side wall 1 of a liquid tank, and gas storage chambers 3b, 4b are formed on extending parts 3a, 4a in the side direction of these fetch ports, 3, 4. Pressure of a liquid to be measured 2 is transferred to a differential pressure detector 9 constituted of a diaphragm and a pressure transfer liquid, through gas of these storage chambers 3b, 4b, differential pressure being propotional to the density of a liquid does not make a liquid of high temperature to be measured contact directly, and does not change the pressure transfer liquid in quality either, therefore, the density is measured stably extending over a long period.
