The description of this item's intended function is fraudulent. The only meaningful measurement for 'How much propane do I have left?' is the amount of liquid in the tank, and this item does not provide that information at all. That must be determined with a float device (measuring liquid level), or by knowing the full (or empty) and current weight of the tank (measuring pounds of liquid.)
The pressure in a tank of any liquified gas is created by the liquid turning to gas, not by pressure being pumped in during filling. (Lookup 'vapor pressure' if you want the science.) There are variables for temperature, altitude, etc., but the vapor pressure is basically constant right up to the point where the last of the liquid vaporizes, then you're done.
During use, the GasWatch gauge will read 'full' for hours while there is still liquid present, then drop to '0' within minutes. This might save the steak you have on the grill, but serves no purpose at all in planning your next event or RV outing. You are better off picking up the tank and sloshing it around to estimate what is remaining.
That said, there are propane tanks with the internal float and gauge built directly into the tank valve. The GasWatch gauge is not that thing. Don't be fooled.
I would have given this zero stars if possible, and don't even know how a product like this is legal to sell.

This product uses PRESSURE to measure LEVEL = WONT WORK. Ever wonder why they dont sell "level guages" WITH the tanks? EVEN IF they work correctly, they will show full as long as there is 1 drop of liquid propane, then all of a sudden they show empty. It's just simple high school physics. Check the link gang! Save your money. Oh, yeah, all these types of home bbq tanks have overfil protection INSIDE them by law. Be an informed consumer. Your friend, chemical engineer, busting myths.
Use this gauge as a general indication of tank level only, dont expect the greatest results. Take the $20 that you would spend on this device and apply it towards purchasing a second propane tank. That way if one tank runs out you have another to replace it with while you go and exchange the empty. You'll always have propane!
The other day I saw a plastic bag labeled, "THIS IS NOT A TOY"... and I wondered to myself who would need to receive that little pearl of wisdom. Then... I read some of the negative reviews for this product...
Let's start here: If you are unwilling and/or unable to read the instructions (written in English by someone who understands English), then do not by this product. If you think this is going to attach to your tank and miraculously tell you the level of propane under any and all use cases, you will not be pleased.
If, however, you do read the instructions, the key section is the following:
"REMEMBER: Allow propane to flow for at least 5 minutes before checking the gas level on the gauge. It is best to read propane level just before finishing the use of gas appliance and determine whether to refill the tank before next use."
Prior to the above `reminder', the instructions clearly note, "... gauge provides reading while propane is flowing..."
WHILE PROPANE IS FLOWING
As usual, using Amazon Prime, my gauge arrived two days later for free. The gauge installs just as easily as your appliance supply line connects to the tank. The assembly swivels and pivots in all directions, so you should be able to adjust the display so it's easy for you to read in your installation. (Something I note under the category of `thoughtful touch', the needle on the display is made of `glow-in-the-dark' materials. While my patio is relatively well lit with torches, it's nice to know that I won't need a flashlight to check the reading after dark.)
Once you are hooked up, the leak check is a breeze.Read more ›

Very helpful. We use two of these for our trailers in our mountain campground. Accurate and easy to attach.Published 2 months ago by Cruise Boy
I bought 2. One for me and 1 for my son. Both of them jammed up and did not permit normal gas flow. The gauge works ok, but the pass through fails.Published 7 months ago by Jay Altieri
It helps me to easy determine when do I need a gas cylinder replacement with just a look to the gaugePublished 8 months ago by Cesar Murillo
Great - works just as advertised and is pretty accurate. After the indicator went to low, I had around 3 more short grills before it was completely out.Published 8 months ago by Mundo
