Abstract
The invention relates to a measurement device (12) for determining a fluid fill level (14) in a fuel tank (10) for a vehicle. The position of a float (18) in relation to a signal generating unit (22) which can be attached on the fuel tank (10) can hereby be converted into a signal that is correlated with the fill level (14) of the undeformed fuel tank (10). A correction device (48, 54, 56) is designed for measuring a deformation of the fuel tank (10) and is used for correcting the signal. The invention also relates to a method for determining a fluid fill level (14) in a fuel tank (10) for a vehicle.
Claims12
A measurement device for determining a fluid fill level in a fuel tank of a vehicle, comprising:
- a float,
- a signal generating unit fastened on the fuel tank, wherein a position of the float a relative to the signal generating unit is converted to a signal which correlates with the fluid fill level of an undeformed fuel tank, and
- a correction device configured to determine a deformation of the fuel tank,
- wherein the signal is corrected with the correction device to account for the deformation of the fuel tank.
A method for determining a fluid fill level in a fuel tank of a vehicle, comprising the steps of:
- supplying with a signal generating unit a signal indicating the fluid fill level,
- measuring a deformation of the fuel tank, and
- correcting the signal based on the measured deformation.
