Method for measuring fluid level |
摘要 |
A method for measuring fluid level uses data sensed by an oil level sensor to determine the level of oil in a motor vehicle oil pan. The oil level sensor can include a receiver tube oriented upright in the oil pan of the vehicle. A level tube is disposed in the receiver tube and below the level tube is a reference tube. A circuit is electrically connected to the tubes for outputting a signal representative of oil level in the oil pan. As the engine oil level decreases within the level tube, the output of the sensor drops. The method includes providing a series of signals to the sensor and recording the output from the sensor with the sensor in a variety of configurations. This information is then processed to determine the ratio of measured oil in the oil pan to the proper operating oil level.
