  • Sensor for level and turbidity measurement
    Patent number: 11467019
    Abstract: The present invention relates to a monitoring system for measuring and communicating properties of a liquid, wherein said monitoring system is configured to be arranged in a mounted position above and at a distance from a surface of the liquid, and wherein said monitoring system comprises: a light source configured to emit light towards the surface of said liquid, such that at least a portion of said light is transmitted through said liquid; a light detector configured to detect light that has been emitted from said light source and transmitted through said liquid and to generate a representation of the intensity and spatial distribution of the emitted light that has been detected; a processing circuitry being configured to determine the turbidity of the liquid based on said representation.
