LCI Lippert Bottlecheck Bluetooth GAS Gauge - Twin Sensor Kit.

Check propane tank levels using BottleCheck Bluetooth sensor and smart device application. BottleCheck can measure the LPG level and when the tank is empty.

BottleCheck can be used on tanks in RVs, caravans, heaters, BBQ grills, etc. BottleCheck sensors are magnetically attached to the bottom of propane tanks.

The sensors periodically measure propane levels and wirelessly send the fill level to the BottleCheck app. This technology is patent pending.
