ACOUSTICS BLOCK OF AN ULTRASOUND MEASURING ARRANGEMENT Russian patent published in 2007 - IPC G01F23/28 

FIELD: the invention refers to technique for measuring the level of liquid and free-flowing substances and for measuring consumption of the substance.

SUBSTANCE: the acoustics block has a sound conduit fulfilled in the shape of a tube inside which on its upper end there is a rigidly fastened electric converter directed with its radiating surface with the aid of the sound conduit to the surface of the controlled medium present in a reservoir, a connector assembly rigidly connected with the reservoir. Additionally there is a flexible suspension whose one end is connected with the aid of the connector assembly with the mentioned reservoir and with other end it is connected with the exterior upper end of the sound conduit so that vertical position of the sound conduit remains. The connector assembly is fulfilled in the shape of a branch pipe whose upper part is connected with a bolt connection with a flange on whose upper part there is an output commutation unit and to the low part of the mentioned flange the upper end of the suspension is fastened, low end of the suspension is connected through a cylindrical bushing with the exterior upper end of the sound conduit with the aid of a screw connection.

EFFECT: increases accuracy and stability of readings at temperature changing and other factors causing mechanical deformations of reservoirs.
