A system for in-situ identification of a working fluid disposed in at least one piece of equipment, said system comprising: a working fluid reservoir that contains said working fluid; an in-situ sensor (403, 405) disposed in said working fluid reservoir characterized in that: the in-situ sensor detects properties of said working fluid or computes properties from the generated spectra of said working fluid; and in that the system further comprises: a transmitter that transmits detected spectra of said working fluid and equipment identification information; and a cloud computing system (411, 412) that receives said detected spectra and said equipment identification information transmitted from said transmitter, wherein said cloud computing system compares said detected spectra and equipment identification information against a reference database to determine whether or not the detected spectra of the working fluid substantially matches the stored reference spectra associated with the expected or specified fluid for said equipment. a working fluid reservoir that contains said working fluid; an in-situ sensor (403, 405) disposed in said working fluid reservoir characterized in that: the in-situ sensor detects properties of said working fluid or computes properties from the generated spectra of said working fluid; and in that the system further comprises: a transmitter that transmits detected spectra of said working fluid and equipment identification information; and a cloud computing system (411, 412) that receives said detected spectra and said equipment identification information transmitted from said transmitter, wherein said cloud computing system compares said detected spectra and equipment identification information against a reference database to determine whether or not the detected spectra of the working fluid substantially matches the stored reference spectra associated with the expected or specified fluid for said equipment. the in-situ sensor detects properties of said working fluid or computes properties from the generated spectra of said working fluid; and in that the system further comprises: a transmitter that transmits detected spectra of said working fluid and equipment identification information; and a cloud computing system (411, 412) that receives said detected spectra and said equipment identification information transmitted from said transmitter, wherein said cloud computing system compares said detected spectra and equipment identification information against a reference database to determine whether or not the detected spectra of the working fluid substantially matches the stored reference spectra associated with the expected or specified fluid for said equipment. a transmitter that transmits detected spectra of said working fluid and equipment identification information; and a cloud computing system (411, 412) that receives said detected spectra and said equipment identification information transmitted from said transmitter, wherein said cloud computing system compares said detected spectra and equipment identification information against a reference database to determine whether or not the detected spectra of the working fluid substantially matches the stored reference spectra associated with the expected or specified fluid for said equipment.
