ACOUSTIC BLOCK OF ULTRASONIC MEASURING DEVICE Russian patent published in 2009 - IPC G01F23/28 

FIELD: physics, measuring.

SUBSTANCE: invention concerns the measuring technics. Ultrasonic block of the ultrasonic measuring device containing a sound line, executed in the form of a pipe. Inside the sound line on its upper extremity the electroacoustical transformer converted by the radiating surface to a surface of controllable medium, being in the tank, and the connecting knot rigidly related to the tank is rigidly anchored. Thus, the sound line is executed truncated to the underload size necessary for formation of the demanded directional diagramme of radiation, and in the inferior part of the sound line holders to which inferior extremities the fiducial mirror is attached, are anchored.

EFFECT: increase of accuracy and stability of measurings at simultaneous reduction of mass and dimensions parameters.
