Abstract
A sensing device for obtaining optical density or light scattering measurements or other, in a turbulent liquid comprising a light source and a facing sensor located within a housing. The housing is provided with orifices through which liquid flows into the housing for measurement. The liquid entering the housing is slowed by passage through the orifice, and the bubbles of the liquid rise to the upper region of the housing, out of the measurement region, e.g. out of the line of the sight between the light source and the sensor.
