Ultrasonic linear array sensor with a resonance frequency of 40kHz was applied to measure the two dimensional granular surface profile in the plane of the vertical section in a hopper. The phase delay compensation beam forming algorithm was adopted for the data processing. The profile was depicted by detecting the incident angle of the reflection from the surface and its travel time. The effect of the instrument configurations, such as the number of array, the distance between the receivers, and the measurement distance, were studied experimentally. The cffectiveness of the application was confirmed by the results for fundamental profiles generally formed in a storage.
