APPARATUS AND METHOD FOR MEASURING AMOUNT OF STOCK IN SILO BY USING SOUND WAVE

摘要

PURPOSE: An apparatus and a method for measuring an amount of stock in a silo are provided to precisely measure the amount of stock in the silo by analyzing a phase difference of a sound wave signal reflected from an object to be measured. CONSTITUTION: An object(A) to be measured is stored in a silo(100) having a predetermined size. A measuring unit(110) is mounted at a predetermined upper position of the silo(100). A control unit(150) is connected to the measuring unit(110) through a wire/wireless manner in order to control the operation of the measuring unit(110) and to display the amount of stock in the silo(100). A horn(102) for receiving/transmitting a sound wave and a connecting member for allowing the measuring unit(110) to be coupled to the upper portion of the silo(100) are integrally formed with the measuring unit(110). Signal transmitting/receiving sections are provided to transmit/receive the sound wave.
