Scored out of 100: 45% customer rating, 30% review volume, 25% features. How we rank
For big home tanks out in the yard.
The standard for grill and RV tanks: it reads the level through the steel.
Mopeka's universal sensor with up to five years of battery.
Checks your home tank from anywhere, with no Wi-Fi needed.
The cheapest way to see your grill tank level on your phone.
Weighs the tank instead of reading through it, so it works on any material.
Most stick to the bottom of the tank and measure the liquid level with ultrasound; others replace the gauge on large tanks. The app shows the level and alerts you before you run out.
Bluetooth sensors only update when your phone is nearby. Wi-Fi models or a Wi-Fi bridge send alerts from anywhere.
Check the tank sizes listed. Grill tanks (20 lb) and large home tanks usually need different models.
