摘要

This invention, the service fluid to the engine of the machine and the especially vehicle while processing which it fills up, method and the device which detect at least the index of 1 kinds of optical absorptivity automatically the fluorescent characteristic which is included in the liquid service fluid and/or regards. According to this invention, this detection with the measurement road (2), emits to the service fluid which it should detect making use of one illuminant (3) at least, passes the service fluid with the measurement road (2) and captures the light (14) which radiation is done from the index which is included in the service fluid and/or by fluorescent action with the optical receiving container (5), strength of that light, has reached the point where influence is received at least with the index or the density of 1 kinds, to form one which reproduces the strength of the light which hit against the optical receiving container measurement signal (8 and 9) at least, appraisal unitWith (10) you appraise one measurement signal (8 and 9) at least, you do by comparing with the value which is retained.
