A fluid level sensor system for a vehicle oil pan includes a fluid level sensor assembled to the oil pan which has a first LED/phototransistor sensor electrically arranged and responsive to a low oil level in the oil pan for generating a low level voltage signal. The fluid level sensor also includes a second LED/phototransistor sensor which is electrically arranged and responsive to a high oil level in the oil pan for generating a high level voltage signal. The low level voltage signal and the high level voltage signal from the fluid level sensor are electrically connected to an electronic control module (ECM) which receives and processes the two signals and activates a warning lamp with a flashing illumination to identify a low oil level condition and a constantly on illumination to identify a high oil level condition. The operation of the ECM is controlled by a flow logic algorithm.
A fluid level sensor system operable to indicate either when the fluid level in a movable reservoir is below a predetermined low level limit or when the fluid level in the reservoir is above a predetermined high level limit, said fluid level sensor system comprising:
An oil level sensor for a movable vehicle oil pan for providing either a low oil level signal or a high oil level signal when the oil level in the oil pan is outside of an acceptable oil level range, the oil pan having the ability to assume different tilt angles, the tilt angles defining a plurality of cross over points based upon the fluid level in said vehicle oil pan, said oil level sensor comprising:
A fluid level sensor system operable to indicate either when the fluid level in a movable reservoir is below a predetermined low level limit or when the fluid level in the reservoir is above a predetermined high level limit, said fluid level sensor system comprising:
