FIELD: measurement of flow rate of medium carrying abrasive inclusions passing over large-diameter pipe-lines. SUBSTANCE: pressure transducer comes in the form of tubular body with inlet branch pipe, section-diffuser, length with maximum section, section-contraction and outlet branch pipe. First row of longitudinal ribs is located in area of transition from inlet branch pipe to diffuser, second row of longitudinal ribs is positioned in outlet branch pipe. Ribs can have rectilinear or wave-shaped configuration. They have preset dimensions and are placed in diametrical planes. EFFECT: high accuracy of measurements thanks to reduction of summary pressure losses in flow. 7 cl, 5 dwg
