Superior technology makes the difference
Why does SeeLeveL perform so well in comparison to other monitoring systems? The sender is externally mounted to the tank eliminating sewage buildup that causes false readings on probe-type sensors. With excellent precision, tank levels are displayed in percent-full. A wide range of models is available for various applications.
Although the SeeLeveL system was originally designed for RVs, it will also work on holding tanks in marine vessels, ice houses, tiny houses, and more.
