ARRANGEMENT FOR DEFINITION AND/OR CONTROL OF AT LEAST ONE PHYSICAL OR CHEMICAL PARAMETER OF THE PROCESS OF MEDIUM IN CAPACITY Russian patent published in 2008 - IPC G01F23/296 

FIELD: invention refers to an arrangement for definition and/or control of at least one physical or chemical parameter of the process of medium.

SUBSTANCE: arrangement has at least one block capable to mechanical vibrations (1) and at least one receiving-driving block (8). The block has a tube (2) and an inner vibrator (3). The tube (2) with its end (4) directed from the process is connected with a fastening block (5), and the end directed to the process (6) of the tube (2) is fulfilled in the shape of a free end. The fastening block directly or if necessary through an additional element is connected with a capacity in which there is medium. The tube (2) encircles an inner vibrator (3), which is fastened with its directed to the process end (7) is fastened on the end (6) of the tube (2 directed to the process. The receiving-driving block (8) excites vibrations of the block (1) capable to mechanical vibrations or receives vibrations of the block (1) capable to mechanical vibrations. According to the invention the inner vibrator (3) has at least one groove/reduction which defines at least the frequency of vibrations of the block (1) capable to mechanic vibrations.

EFFECT: increases accuracy of measuring.
