FIELD: testing parameters of gas and liquid system. SUBSTANCE: method consists in recording of acoustic vibrations inside resonance tube partially submerged into liquid, in their conversion to electric signal, in generation of spectral characteristic of this signal, in determination of frequency of following of resonance peaks in spectrum, in setting of standard value of frequency of following of resonance peaks in spectrum, in its comparison with determined frequency of following of resonance peaks in spectrum, in obtainment of information on level of liquid, temperature of gas and liquid system, molecular weight and composition of gas in system. Invention describes gear realizing given method. EFFECT: increased authenticity and accuracy of method and gear. 2 cl, 2 dwg
