Never run out of propane unexpectedly!! Monitor the LP gas level in your tank accurately by ultrasound technology and monitor it with your smartphone or tablet via Bluetooth signal! Simply attach the magnetic sensor to the bottom of your tank and use a downloaded app on your mobile device for initial calibration and then monitoring of your tank level. Fuel tank level is updated every 5 seconds when the device is within 150 feet of the sensor - good information while grilling on a gas grill. Mobile app can support multiple tank monitors! A Bluetooth monitor is available for mounting inside the RV.
