This application is designed to be used with the GasNow GasCheck sensor. The GasCheck application can measure the LPG propane level to tell you the exact fill level and when your cylinder is empty. It can be used on cylinders found in RVs, heaters, BBQ grills, etc. The Gas Check sensors are magnetically stuck to the bottom of your propane cylinder and will periodically measure and wirelessly send the fill level or percentage to the Gas Check app. Stick it on the bottom of your cylinder and know exactly when you are running low on propane! This technology is patent pending.
1. To pair your Gas Check sensor to the phone, simply press the "Sync" button on the back of the sensor while the app's main screen is visible. The first time you use your Gas Check sensor you must press the "Sync" button 5 times in a row in order to wake up the sensor.
2. Place the Gas Check sensor in the center of the underside of the cylinder. Most cylinders have a small "flat" spot on the center and this is the nominal location for the sensor.
3. Flip the cylinder over. Once the fluid has settled the app will display a reading. Note that the LPG fluid will be sloshing around in the cylinder for a few minutes and the quality of the measurements will be low until this has stabilized.
