Abstract
A measuring device for measuring the concentration of particles in a liquid advanced through a tube (2) includes a transducer where the tube in a measuring zone has an area change implemented such that the pipe wall is kept clean from deposits. Probes (8, 9) are inserted in the tube wall (6, 7) so that the measuring surfaces of the probes are in contact with the liquid and form a part of the tube wall. The measuring device is compensated for temperature by means of a reference apparatus (13, 14) coacting with said probes electrically and mechanically.
