Title: Level position detecting device for dispensing machine
Inventor: MIZUKAMI KAZUAKI
IPC: G01N35/10
Filed: 1994-11-24
Abstract: PURPOSE: To precisely measure the distance with a substance to be measured by measuring the round trip time of ultrasonic wave to a standard substance, and then measuring the round trip time to the substance to be measured. CONSTITUTION: A standard substance (surface) 1 is preliminarily provided in a position where the distance L1 from a sensor 4 is known, and this distance is stored in a memory means provided in a controller. When the distance to the standard substance 21 is L1 , and the standard value (time) at that time is T1 , a sound velocity C is shown by [expression 1] C=2L1 /T1 . Thereafter, the direction of the ultrasonic sensor 4 is directed to a substance to be measured within a sufficiently minute time, and measurement is performed to the substance to be measured, or a subject in a plate 6. When the distance to the substance to be measured is L2 , and the time until the reflected wave returns is T1 , the sound velocity C is shown by C=2L2 /T2 .  When two measurements are performed within a minute time, the sound velocities are equal to each other since the temperature change between them can be substantially ignored. Thus, the precise distance L2 to the substance to be measured can be measured by L2 =(T2 /T1 )×L1 without determining the temperature-corrected sound velocity. After the measurement, dispensing operation is performed, and the measurement of the standard wave is successively executed.
