FIELD: investigating density and specific gravity of materials.
SUBSTANCE: device has vibration unit secured to the diaphragm, receiving-transmitting block, and block for control and processing. The vibration unit is positioned at a given level of filling. The receiving-transmitting block excites oscillations in the diaphragm and vibration unit at a given frequency and receives the oscillations of the vibration unit. The block for control and processing determines when the actual level of filling reaches a given level of filling.
EFFECT: enhanced reliability of measurements.
