Abstract

A turbidity sensor or an arrangement for optically measuring one or more physical, chemical and/or biological, process variables of a medium. The medium is located in a pipe. The arrangement includes a housing and the housing is embodied for securement in the pipe. The housing is embodied for accommodating at least one light source for sending light through a window region into the medium and at least one light receiver for receiving light through the window region from the medium. The light is scattered by the medium and the light intensity received by the light receiver is a measure for the physical, chemical and/or biological, process variable, characterized in that the light source is so arranged that the light propagates in the medium in the longitudinal direction of the pipe.
