Bluetooth Propane Level Detector
Winner: LP Tank Check Dual Sensor with Monitor Kit
This was one of the best additions I ever made to my RV. On more than one occasion I ran out of propane at inopportune times (read: the middle of the night, in Illiniois, in winter) and wished for a way to quickly and easily figure out my propane levels. Sure, there’s the hot water method, or rapping on the cylinders to get an idea, but honestly being able to pull my phone out of my pocket and check instantly is not only super useful, it’s very gratifying.
Setting these up is quite easy – they attach magnetically to the bottom of your propane tanks. First, use the included lifts which attach to the bottom of the tank (this gives the tank a little bit more clearance to allow room for the sensor) and then simply place the sensor in the center. There is a quick pairing process which simply involves pressing a button on the sensor and the app (available for iPhone and Android) does the rest. The unit also comes with a physical meter which can be mounted if you prefer a gauge mounted somewhere in your RV rather than using your phone.
A couple of quick notes: first, the unit I received had some rubber lifts (mentioned earlier) which were constantly falling off. I believe the company has rectified this issue, and when I contacted them they sent me some aluminum lifts right away and at no cost. Second, this only works when you’re within Bluetooth range. The company does offer a ‘wifi bridge’ at an additional cost if you’d like to be able to monitor your tanks from anywhere (and you have a wifi network running).
Overall – I highly recommend this product and personally can’t live without it.
