how accurate are the sensors and propane sensor for levels

Nothing beats the old fashion way.
Poor boiling water on the tank.
Run your finger from bottom to top on the side of the tank.
When it's to hot to touch that's your level.
Do it once a day and you'll get a feel for how much is used in a day.

Propane bottles keep a constant pressure inside till they are almost empty, so a pressure gauge is a joke. Google propane level check for a variety of ways to check level, but realize that the only correct reading is by measuring weight. I have two bottles and keep one closed for two reasons; one, the auto change over regulators can fail; and two, I want to know when a tank empties without constantly looking at a rather inaccessible flag.

A 30 lb. bottle lasts me about a month with some cooking and some electrical hookups. YMMV

Some one suggested that you fill your water tank and use it for a week end and then check your consumption, well do the same thing with the propane.

In general, most fridges of the same year and model will use the same amount of propane per hour, do you have the same kind I have and is the temp setting the same? If so we filled up with propane, camped for six weeks, came home, set for awhile, went back out for four days, now back home, we have propane left, you should too.

just the frig ,can run for weeks ,its use is very little and dose not burn constantly. other gauges are not trust worthy .in our poo tank we put in couple caps full of dawn dish soap ,helps keep things a little cleaner.

The sensor is right over the gage so I cant read it

They are very accurate, when the propane runs out it will read zero. At all other times, useless.

Your fridge will go a very long time on a bottle of propane.

So right now I says 2/3 full and it may be almost empty ?? WTH so is there a better way to check level ? And what is a "very long time" ?
Days, weeks, hours ?
