摘要

The arrangement has a handle (6) mounted outside the reservoir and a measurement device (1) within the reservoir about a flexible element (2), e.g. a metal wire. The measurement device has openings (3) extending at least partly over its circumference near maximum and/or minimum levels. The openings are annular grooves extending over more than 180 deg .
