Residual liquid meter using computer responsive to measurements of liquid level and flow

摘要

An automotive vehicle residual-fuel meter uses a microcomputer into which a signal indicating initial fuel tank liquid level is set. The initial setting is reduced in response to fuel consumption pulses derived from a ball-oscillation flow meter. The computer drives a residual fuel indicator. To increase the residual fuel quantity indication accuracy, a plurality of fuel level sensors, such as thermistors, correct the residual fuel indicator.
