The device for determining the physical attributes of liquids is used in the production of devices, determining the physical attributes of liquids, such as isothermal and adiabatic compressibility, density, the coefficient of thermal expansion, speed and the adsorption of ultrasound, precise measurements, according to the coefficient of thermal receptivity, other thermo physical and thermo dynamical quantities, potentials, functions are determined. The device consists of high pressure housing (1) with a measurement chamber, piston (8), a block (14) for initiation, the receiving of signals, the registering and processing of data, a changer of oscillations (5), mounted inside the chamber and composed of two measurement sections attached to each other, they have a stable (6) and changing (7) acoustical bases. Between the piston and the changer of oscillations, a sliding piston liner (17) can be mounted. This device improves the preciseness of the measurement of physical attributes of liquids in different pressures, volumes and temperatures. |
