Never run out of propane again with this ultrasonic propane tank gas level sensor and Bluetooth phone app! Slap the sensor on and open your app, it's that easy. Once you have your reading, remove the sensor and toss it in your glovebox. The Mopeka Tank Check sensor measures the LPG propane level to tell you the exact fill level and when your tank is empty. The sensor is magnetically stuck to your propane tank and will periodically measure and wirelessly send the fill level or percentage to your Tank Check app via Bluetooth. This product requires calibration based on the diameter of the LP tank cylinder. • Bus/Vanagon LP Tank diameter: 6" • Oversize Vanagon Tank diameter: 8" • Eurovan LP Tank diameter: 8" App is available for both iOS and Android. See your app store for the free download. Installation Notes Install tips: The instructions direct you to install the sensor on the bottom of a vertically mounted tank, however, for a horizontally mounted tank place the sensor perpendicular to the tank so that most of the body hangs off. Be sure to remove the sensor before driving off, we cannot confirm that these will stay put on the road.
