【Abstract】 The working principle,structure design,technical study and signal processing technology of flow velocity transducer are explained.Based on the Pitot tube principle for measuring the medium flow velocity,the sensor uses the differential pressure sensor to measure the hydrototal pressure and static pressure difference.The water flow direction indicator principle is adopted to measure the flow direction,the magnetic resistance chip is used to detect the angle,single chip processor is used for data collection and followup processing.The sensor has the characteristic of wide measuring range,high accuracy,resistance to high static pressure,high resolution,antivibration and antishock and corrosion resistance.It is also the same with deepwater midstream measurement.更多还原
