Device is mainly intended for control of density of gas-saturated emulsion explosive in well during drilling and blasting operations, however, can be used for controlling density of liquid media of different viscosity and in any other vertical channels. Method of measuring density of liquid media consists in measuring pressure at two levels and subsequent calculation of average density between levels, at which measurements are taken. In the liquid medium there are gas-filled chambers connected to each other and by the measuring device, closed by movable membranes with limited mobility and vertically spaced for a certain distance. Cameras have mechanism, causing change in optical signal reflected or generated directly in chambers during membrane movement through the pressure balance position between the inner cavity of the chambers and the monitored medium. Membranes are actuated by injecting air into the gas communication connecting the chambers and the external measuring device. Optical indicator of equilibrium position of membranes is connected to external measuring instrument by means of optical fiber passing inside gas communication. Optical signal from the upper and lower chambers is characterized by a spectrum. Therefore, by measuring, it is possible to distinguish which of membranes has passed the equilibrium position corresponding to hydrostatic pressure. Measuring pressure in gas communication at moments of generation of optical signals, obtaining two values of hydrostatic pressure, corresponding to the depth of location of two gas-filled chambers, through which is then calculated average density of emulsion explosive or other controlled medium at depth of gas-filled chambers.
