Abstract: A fluid level measurement apparatus supports multiple fluid level sensors of different types, each of which detects a level of fluid and produces an output indicative of the detected fluid level in a different way. The fluid level measurement apparatus is connected to any one of the supported fluid level sensors to measure the fluid level. The fluid level measurement apparatus includes a calculation circuit, multiple output circuits, a determination circuit, and a selection circuit. The calculation circuit calculates the fluid level from a detection voltage. Each output circuit generates the detection voltage based on the output of a corresponding fluid level sensor. The determination circuit determines the connected fluid level sensor. The selection circuit selects the output circuit corresponding to the determined fluid level sensor and allows the calculation circuit to obtain the detection voltage generated by the selected output circuit.
