Needed a reliable level indicator for 3 tanks, because the tanks are no longer transparent due to age. Looking on the internet, there were different models in cm to digital displays are to show up at the exact liter oil level from simple display of levels. Buderus was also unbeatable in comparison. Ok it only displays the level in cm and is determined not 100% accurate. But this is not a problem for me, because it indicates reliably when it is time to reorder oil. The indicators were delivered promptly and were very easy to install. Have these indicators installed at a total of 3 tanks and all work to the utmost satisfaction. Can I recommend.
