Inventor: ISHIDA KAZUO
IPC: G01N9/00
Filed: 1989-09-06
Abstract: PURPOSE:To exactly measure the filling height of pearlite by vibrating freely an outer tank to which an accelerometer is attached. CONSTITUTION:An accelerometer 11 is attached to an outer tank 2 of a double shell low temperature storage tank with an adhesive tape, etc., the outer tank is vibrated freely by tapping lightly the vicinity of the accelerometer 11 with a hammer 13, and an attenuation waveform of acceleration at that time is recorded in a recorder 12. In the case the accelerometer 11 is attached to the outer tank 2 part which is not filled with pearlite 3, the attenuation of vibration is slow, and after the excitation, the vibrating state is continued for a considerable time. In the case the accelerometer 11 is attached to the outer tank 2 part filled with the pearlite 3, the attenuation of vibration is quick, and after the excitation, the attenuation starts immediately, and the vibration ceases to exist in a short time. Therefore, after the accelerometer 11 is moved in the vertical direction and fixed, the filling height of the pearlite 3 is measured exactly from a difference of the attenuation waveforms recorded in the recorder 12 by tapping lightly the accelerometer with the hammer 13 and repeating the excitation.
