DEVICE FOR MEASURING DENSITY OF LOOSE MATERIAL Russian patent published in 2004 - IPC

FIELD: investigating or analyzing materials.

SUBSTANCE: device has a permanent source of gas, air vessel, generator of acoustic oscillation made of a diaphragm, and generator of flat acoustic wave connected to the air vessel. The open end of the generator of flat acoustical wave faces the surface of the matter to be investigated. The device for moving is connected to the movement meter . The meter provides the movement of the air vessel with respect to the surface of the matter. The device is also provided with control block, jet turbulence e amplifier, mass meter, and computing block. The measuring vessel is connected with the mass meter whose output is connected to the first input of the computing block whose second input is connected with the output of the movement meter.

EFFECT: expandable function capabilities.
