ABSTRACT:
Methods and systems for detecting filter rupture are provided. The system includes a light emitter positioned on a first lateral side of a fluid flow and configured to emit light at a predetermined intensity into the fluid flow downstream from a fluid filter, a light receiver positioned on a second lateral side of the fluid flow and configured to receive at least a portion of the emitted light, and a controller configured to receive a signal from said light receiver corresponding to the intensity of the emitted light or the pulsations in the light received, also known as scintillation, said controller configured to generate a corresponding output signal.
