FIELD: measurement technology. SUBSTANCE: several ultrasonic rays are let pass through transferred medium in at least three different planes along flow and $$$ scanning of medium is conducted simultaneously. Velocities V1, V2, V3 in these planes by which integral velocity V of flow is calculated are measured. Density of medium, type and brand of transferred product are calculated by attenuation of intensity of flux of $$$ radiation and measured velocities C1, C2, C3 of sound. Area of section of measurement length is determined by means of one-time preliminary scanning by $$$ radiation. EFFECT: enhanced authenticity of process. 1 dwg
