A method and system for detecting foreign particles in a liquid, the method and system include transmitting transmitted pulses of radiation, by a transmitter, towards a liquid conduit that is filled with liquid; wherein the transmitted pulses comprises pulses that differ from each by being associated with absorbance frequencies of different foreign particles; receiving, by a receiver, received pulses that propagated through liquid as a result of the transmission of the multiple transmitted pulses; comparing between the transmitted pulses and the received pulses to provide a comparison result; and determining a liquid contamination based on the comparison result. |
