A new instrument for measuring turbulence is introduced in this paper. The transducer of the device is based on the principle of the effect of the silicon piezoresistance, which is integrated in the Wheatstone bridge on a pure silicon beam. At one end of the beam, a small light ball is installed as the target forced by the water flow. The instrument is equipped with a microcomputer inside. The instrument can be used to measure turbulent velocities and either in clear water or in flows bearing hyperconcentration of sediment.展开更多
