Ultra Sound wireless LP tank sensor , Bluetooth to phone app

If you have a built in ASME LP tank installed on your RV such as on most Class A's and C's, the Mopeka sensors can also be used on them. The app can be configured for the horizontal tank and the tank height entered in inches. I would recommend securing the sensor with something like Gorilla tape though, instead of depending on just the standard magnets for travel. The tape could also provide some protection from road debris damage.
