Yes, propane tanks can be tracked. There are a few different ways to track a propane tank. The most common way is to use a GPS tracker. This is a small device that can be attached to the tank. The tracker will then send out a signal that can be tracked by a satellite. This method is very accurate and can tell you exactly where the tank is at all times.
Another way to track a propane tank is by using an RFID tag. This is a special type of tag that emits a signal that can be picked up by an RFID reader. This reader can then be used to track the location of the tag. This method is not as accurate as GPS tracking, but it does not require batteries or any other type of power source.
The third way to track a propane tank is through the use of barcodes. Barcodes are usually printed on the side of the tank in order to identify it. These barcodes can be scanned by a barcode scanner and this information can then be used to track the location of the tank. However, this method is not as accurate as GPS or RFID tracking methods.
