3. The device for measuring object volume consists of two sets of chambers, a measurement set and a reference set, each connected to the differential pressure gauge and a converter of the difference into an electric signal. Unique characteristics: The measured object (3) is introduced into one measurement chamber (4) in the set of two measurement chambers. The chamber is connected to the chamber (6), containing at least one plunger system (1). The set of two reference chambers contains the reference chamber (13) connected to the other reference chamber (11), containing at least one plunger system (15). The set of measurement chambers (4, 6) is connected to the set of reference chambers (11, 13) by means of the duct (9) with the ventilator (8). Each set of measurement chambers (4, 6) and reference chambers (11, 13) is connected to the duct (9) through the valves (7) and (10), respectively, and to the surrounding space through valves (5) and (14), respectively. The gauge and the converter (16), the valves (5, 7, 10, 14), the sets of plungers (1, 15) and the ventilator (8) are connected to a computer or a microprocessor system (17). |
