The Wireless ALTA Propane Tank Monitor allows a user to remotely monitor the level of a propane tank by simply plugging in the R3D® (Remote ready) sensor into a pre-installed R3D tank gauge. As the propane level is decreased, the reading produced decreases as well. The monitor converts the reading into a percentage of propane remaining in the tank and transmits that percentage wirelessly to its connected ALTA Gateway. The percentage depends on the configuration of the tank and the R3D gauge pulling an accurate level of propane inside.

Important:Tank gauges that are not R3D ready can be upgraded with an R3D gauge from one of these vendors:

Warning: If you do not have a dial that is R3D compatible, do NOT attempt to change the dial yourself. Please contact your propane supplier and ask them for a replacement dial that supports the R3D standard. The float gauge inside the tank does not need to be replaced, just the plastic dial that reports the propane level inside the tank. (Compare your dial to those in the following link and verify which one is installed on your tank. If R3D ready, please proceed.)
