Device and method for measuring turbidity

A measuring device, comprising:

• a fluid storage part;
• a reflector coupled to the fluid storage part;
• a first light source configured to emit light toward a fluid located within the fluid storage part;
• a first light receiving part configured to receive scattered light based on the emitted light from the first light source, wherein the received scattered light includes the emitted light after having been scattered by suspended particles in the fluid;
• and
• a controller configured to measure turbidity of the fluid by controlling the first light source and the first light receiving part,
• wherein the first light source and the first light receiving part are spaced at a predetermined angle from each other with respect to an axis of the fluid storage part, and
• wherein the reflector is sized to include a first surface facing the first light source and a second surface facing the first light receiving part.

A measuring device, comprising:

• a structure shaped to define a cavity to contain a fluid;
• a reflector positioned relative to an outside surface of the structure;
• a first light source configured to emit light toward the fluid contained within the structure;
• a first light sensor configured to receive scattered light based on the emitted light from the first light source, wherein the received scattered light includes the emitted light after having been scattered by suspended particles in the fluid;
• and
• a controller configured to measure turbidity of the fluid by controlling the first light source and the first light sensor,
• wherein the first light source and the first light sensor are spaced at a predetermined angle from each other with respect to an axis of the structure, and
• wherein the reflector is sized to include a first reflective portion positioned to face the first light source and a second reflective portion positioned to face the first light receiving part.

A measuring method, comprising:

• receiving an user input requesting a turbidity measurement of a fluid located withing a fluid storage part;
• turning on the first light source and turning off the second light source, based on receiving of the user input requesting the turbidity measurement;
• receiving a first light receiving signal from a light receiving part:
• turning off the first light source and turning on the second light source;
• receiving a second light receiving signal from the light receiving part;
• and
• measuring the turbidity of the fluid, based on the first light receiving signal and the second light receiving signal.
