ABSTRACT:
A fluid level monitor for sensing the level of fluid in a reservoir such as for sensing an oil level in an internal combustion engine crankcase containing a quantity of oil, the monitor includes a light source for generating a light beam having a frequency which causes fluorescence in the fluid and a fiber optic cable for transmitting the light beam to the reservoir for exciting the fluid in the reservoir to generate fluorescent radiation and for receiving the fluorescent radiation emitted by the fluid as a result of the excitation. The monitor also includes a photodetector for receiving the fluorescent radiation and for generating a signal which is a function of the intensity of the received fluorescent radiation and a display for receiving the signal to indicate the level of fluid in the reservoir.
