BMPRO SmartSense - Single Gas Bottle Level Monitor & App Smartsense

HOW DO I CHECK THE LEVEL IN A GAS BOTTLE?

SmartSense, a gas bottle level indicator, eliminates the need for guesswork.

Install the SmartSense app, synchronize the sensor, and fasten it to the gas cylinder's bottom. You may now use your smartphone to obtain an accurate response!

You can choose from the usual Australian gas bottle sizes or set up the size of your own bottle. Set the information to be shown as a percentage or in centimeters, and set the alarm threshold.

Make sure you never run out of gas by using your smartphone to keep track of as many gas bottles as you like.
