FIELD: measurement of flow rate in pipe-line with large cross-section. SUBSTANCE: pressure transducer is made of case joined to pipe-line with built-in member in which longitudinal slit-like groove of variable depth open inwards is formed. Groove communicates with pipe union to tap maximum pressure in point of its maximum depth. Second pipe union for pressure tap is located in groove downstream of first one. EFFECT: increased measurement accuracy as fluid medium flows in pipe-line undisturbed. 2 cl, 4 dwg
