FIELD: physics, measurement.
SUBSTANCE: case of the device holds magnet system of six permanent magnets oriented with one pole to work surface of the case, formed by dielectric coating. Between magnets four electrodes are placed and connected in couples to similar inputs of first and second differential amplifiers of electronic unit. Outputs of first and second differential amplifiers are connected to inputs of third differential amplifier, output of which serves as output of the device. Electrode positioning at rectangle apices allows maximum suppression of electric jamming present in electroconductive medium.
EFFECT: enhanced precision of measurement of electroconductive fluid flow velocity.
