Abstract
Fluid level detector device and method are disclosed, for determining the height level of one or more immiscible fluids in a vessel. The device includes at least one optical set-up including a light source for generating a beam of light of predetermined width and optical characteristics, the light beam arranged to be directed into the fluid so as to cause refraction of the light beam, dependent on the index of refraction of the fluid, the light beam covering a predetermined detection region. A photosensitive detector is provided capable of generating a signal corresponding to at least one optical characteristic of the light beam after passing the fluid. An interpreter is provided for receiving the signal, interpreting the signal and indicating the height level of the fluid.
