| Abstract: | Presents an ultrasonic thermometry for cross sectional temperature distribution of flowing liquid layers. Pure water as a example was tesed and numerically calculated by F(?) form/Inverse Fourier Transform distribution of sound propagation time measured by the technique. The device is simple, viberation proof and convenient for worksite. |
