Inaccurate measurement, therefore limited usability
After replacing the tank in my sailing yacht a year ago and installing this sensor in the new tank, I was able to test the system extensively. On a tour of 290nm and refueling four times, the donor showed particular problems. In the range below "25%" the display on the tank went empty, but the content corresponded to approx. 30%. Same problem when refueling; Display shows 100%, but the true content was only about 80%. Measuring points every 21mm correspond to a resolution of approx. 9-10%. The result was that from a 50 liter tank content, only 27.5 liters were usable in the monitoring. Absolutely no purchase recommendation.
