FIELD: experimental hydrodynamics, oceanology. SUBSTANCE: device is intended for investigation of hydrophysical fields while conducting ecological studies, in experimental hydrodynamics and other branches of technology where monitoring of parameters of turbulent medium is required. Device includes four identical converters of speed to electric signal and unit computing function. All four converters are placed in one plane, any three converters of above-mentioned four converters do not lie on one straight line. First to fourth outputs of unit computing function are connected to outputs of converters and output of unit is output of device. Best arrangement of device consists in placement of converters in vertexes of square. Thanks to such placement of converters linear dimensions of device are reduced and output signal free of vibration disturbances is secured. EFFECT: reduced linear dimensions of device, generation of distortionless signal. 1 cl, 4 dwg
