FIELD: physics, measurement.
SUBSTANCE: invention is related to controlling and measuring equipment and may be used for measurements of mass flow of liquids transported in oil pipeline. Device comprises two sets from N reversible electroacoustic transformers, two sets from N timers, generator, two amplifiers of high-frequency electric oscillations, four demultiplexers, demultiplexer - decoder "one of 2", four multiplexers, electronic key, two microcomputers. Device is also equipped with meters of density and temperature of oil and meter of oil pressure in pipeline.
EFFECT: higher accuracy of liquid mass measurement due to account of correction for deformation of pipeline cross section stipulated by action of temperature and pressure.
