Title: Measuring method for passing amount (moving amount) of powder, particles and blocks
Inventor: YAMAMOTO MASAHARU
IPC: G01F1/74
Filed: 1992-05-28
Abstract: PURPOSE:To measure passing amount (moving amount) by measuring the vibration sound emitted by the friction and collision between objects and obstacle, objects and side walls and each other objects when the objects move and fall. CONSTITUTION:Measured object is continuously taken out of a resorvoir tank 1 with a vibration supplier 2 and is made to pass on a detection plate 3 placed with an ultrasonic sound microphone 4. The friction sound between the measured object and the detection plate 3 is measured with the ultrasonic sound microphone 4 to make it the passing amount of the measured object. That means, it is making use of that the energy of friction and collision is proportional to the object mass and moving velocity. However, since the rate of contact with the detection plate 3 reduces as the passing amount of the measured object increases, it is sometimes necessary to correct it. By this, selection of measurement method is possible according to the required accuracy conditions and the like, and thus automation becomes possible.
