I’ve been looking for a reliable, accurate, device to measure the level in our black water holding tank in our boat. I also preferred a solution that did not require drilling holes in tank and was compatible with fiberglass tank construction and providing data to our Victron Cerbo GX. Your product met all of my requirements!

Ease of installation, and really precise measuring.

Required simple, non-invasive, meter to warn when blackwater tank needed emptying.
