ULTRASOUND LEVEL METER Russian patent published in 2007 - IPC G01F23/28 

FIELD: the invention refers to technical acoustics and may be used for control of the level of liquid in closed reservoirs.

SUBSTANCE: the device has a receiving-radiating block located on the cover of the reservoir with investigated liquid on its inner side and a an impulse generator attached to it. The receiving-radiating block has a radiating and receiving electrical-acoustic converters and a stepping motor. The invention is directed on increasing of accuracy of measuring and on reliability of the arrangement with simultaneous provision of simplicity of construction. No-contact at measuring and high accuracy of control of the level of liquid mediums is achieved due to using ultrasound level meters.

EFFECT: increases accuracy of measuring.
