A fluid meter has a housing comprising a flow channel for fluid to be measured and at least one elongate module-receiving opening forming a passage from an outer surface of the housing to the flow channel. At least one fluid-measuring module, prefabricated separately, from the housing with a base section formed as a waveguide for surface acoustic waves, and at least one signal transformer to excite surface acoustic waves in the waveguide and/or receive surface acoustic waves from the waveguide is provided. When inserted into the module-receiving opening, the base section of the fluid-measuring module forms part of the flow channel inner wall and contacts fluid flowing through it. Surface acoustic waves emitted by the signal transformer can be coupled out of the waveguide and can propagate through fluid in the flow channel as bulk acoustic waves and/or bulk acoustic waves can be coupled into the waveguide and received by the signal transformer.

A turbidity sensor has a housing, a cuvette for a sample medium, a lighting source, a light sensor, a drying agent and a chamber system. The chamber system includes a central receiving space in which the cuvette is arranged, a lighting chamber adjoined by the lighting source, at least one sensor chamber adjoined by the light sensor, and a drying chamber in which the drying agent is arranged. The lighting chamber, the at least one sensor chamber and the drying chamber are each fluidically connected to the central receiving space. The chamber system is here configured as a passive, pump-free system.
