How to Read a Propane Tank Gauge

Reading a propane tank isn’t that straightforward as there are tanks of different sizes. To ensure all the appliances in your home as well as business run flawlessly, you must know how to read the tank so that you can ask your propane provider to refill it before it’s empty.

When you look at the tank gauge, it only tells you the percentage of total fuel it currently has. That doesn’t tell you exactly how much fuel the tank holds. Herein, you need to calculate considering your tank size to know the exact fuel amount.

In this article, I'll cover how to accurately read the propane tank gauge along with some important aspects related to it.

What is a Propane Tank

As you know, propane is a type of gas which has lots of aspects of usages. When you get a propane tank for your home or business, know that the tank is not filled with propane gas. Propane gas is compressed and stored in the form of liquid inside the tank.

But the thing is, you cannot power your appliances using that liquid. The liquid inside the tank boils when the inside temperature is -44°F. When it boils, it turns some amount of liquid into vapor or gas, and you use this vaporized gas to run your appliances.

Whenever the liquid boils and turns into gas, it decreases certain liquid from its total amount. And when you read a tank gauge, that tells you the amount of liquid left inside.

For example, if the gauge is showing 50% of propane is left, that means you already have used 30% of propane as the tank always fills to 80%.

Why Your Propane Provider Never Fills the Tank over 80%

If your propane provider only fills the tank to 80% and you always ask them to fill it to 100%, know that you are not the only one making such demand. It sounds strange, but not a single provider would deliver a tank full of propane to their customers ever.

When you know the reason behind why they do so, it will make more sense to you. It’s for your own safety. The gas is stored under pressure in a liquid state which expands when the tank is hot. Inside the tank, additional space provides necessary room for the liquid propane to turn into a vapor.

If the tank is full all the way to 100%, there will be no space for propane liquid to expand into gas or vapor and it will cause issues. That's the reason why no matter how large the capacity of your tank is, the provider will fill it with 80% of propane.

Propane gas is greater in volume than its liquid form, and this is why the gas requires more space to store it. Therefore, every propane tank is filled to 80% and leaves at least 20% for the liquid to evaporate and store gas at the top of the tank.

Your home appliances are run using this gas. As you continue to consume the gas, the liquid then boils faster and evaporate more vapor to replace the old gas.

How to Read a Propane Tank Gauge?

Usually, propane tanks used throughout every household and business have the capacity of holding 120, 150, 200, 250, 500, or 1000 gallons of propane liquid. Depending on the size and considering what percentage the gauge is showing, you can know exactly how much propane is left inside the tank.

Now, let's see what the gauge on a 1000-gallon propane tank shows.

When the gauge shows;

  • 80%, there is 800 gallons of propane left
  • 70%, there is 700 gallons of propane left
  • 60%, there is 600 gallons of propane left
  • 50%, there is 500 gallons of propane left
  • 40%, there is 400 gallons of propane left
  • 20%, there is 200 gallons of propane left
  • 10%, there is 100 gallons of propane left

Note that, the gauge never reads 100%, as 80% is considered full.

That was how you need to read the gauge of a 1000-gallon propane tank. But not everyone has a tank of such huge capacity. So, here I’m showing you how to read the gauge and calculate the exact amount propane the tank has regardless of the capacity.

All you need to do is, multiply the percentage that the gauge is showing by the total capacity of the tank.

For example, if your propane tank has the capacity of 500 gallons, and the gauge is showing there is 60% left, the exact amount of propane inside the tank would be 500 x 0.6 = 300 gallons.

Now that you know how to read a propane tank gauge, you can easily calculate and find the exact amount of propane a tank has no matter what the tank size is.

Regardless of the capacity, every propane tank has a fill pipe, a regulator, an emergency vent, a shut-off valve along with a gauge.

 

When is the Time for Refilling?

You don't want your appliances running out of power suddenly. To prevent such an unexpected situation from happening, you need to make sure the tank has enough amount of propane. Therefore, it's suggested to ask your propane provider to refill the tank when the gauge reads below 30%.

Hopefully, this time you will not feel frustrated by seeing you are delivered a tank filled with 80% of propane.
