Claim:
1. A method for measuring of a fill level, comprising the steps of: capturing measured data; generating a digital image of an echo curve, the digital image being made up of a large number of pixels from the captured measured data, wherein the fill level is, determinable from the digital image; identifying a fill level echo in the echo curve; determining a desired first level of detail of a first image region of the digital image, the first image region comprising the fill level echo; determining a desired second level of detail of a remaining second image region of the digital image, wherein the first level of detail is higher than the second level of detail; compressing the first image region by a first factor, which reflects the first level of detail; compressing the second image region by a second factor, which is higher than the first factor, and which reflects the second level of detail; and transmitting the compressed digital image to a control device.
