description The present invention relates to a system for removing deposits from measuring instruments (1) measuring chosen characteristics of a fluid medium contained in a pipe or container (6), the measuring instrument (1) comprising a first surface (10) having contact with said medium, said first surface (10) being positioned on one end defining a probe head (2) of an elongated member (3) adapted to be extending through the wall of said pipe or container (6), the outer end of said member being positioned outside said wall, the cleaning system comprising an acoustical transducer (5) positioned on the other end of said elongated member (3), wherein said acoustic transducer (5) is acoustically coupled to the elongated member (3) so as to couple acoustic energy thereto, the acoustic energy propagating along said member to the end of the probe being in contact with the fluid inside the pipe or contained, the resulting vibrations of which removing any contaminations from said first surface (10) by inducing micro-cavitation.
