The JUMO MAERA S25 level probe can be used for hydrostatic liquid level measurement in tanks, for levels from 2.50 m to 10 mWC (water column). There is usually a pressure compensation tube integrated in the cable to compensate for ambient pressure. A cost-optimizing approach has been adopted for this level probe, by encasing a standard cable in a protective tube. The protective tube then implements the pressure compensation. For additional, interesting information, see the "level probes - hydrostatic level and liquid level measurement" brochure.
