We’re in the midst of outdoor living season in Connecticut, which means it’s time to fire up your propane BBQ grill! Simply ensure that you have extra gas for your next summer BBQ.

However, as any veteran propane griller knows, most 20-pound propane barbecue cylinders lack a gauge, which means you’ll need to figure out how much fuel is left in your tank in another method.

Here are three easy ideas to get you started:

1. Make use of warm water. This safe and straightforward method for determining how much propane is left in your tank was given by the FiX IT Home Improvement Channel. To accomplish this,

- Fill a small bucket halfway with warm to hot tap water and set aside.
- Pour the water down the tank’s side.
- Feel for a cool location around the tank’s side using your hand.

The fill level of the tank is at the top of the cold spot (it’s cool because liquid propane inside the tank absorbs heat from the water, making the tank’s metal wall cool to the touch).

2. Check the tank’s weight. On the handle of most propane grill tanks are two numbers: the water capacity (“WC”) and the tare weight (TW), which is the weight of the tank when it is empty. When empty, most grilling tanks weigh around 17 pounds and store around 20 pounds of gas.

Simply weigh your tank on a scale and subtract the TW number to find out how much propane is left in it. If a 27-pound tank has a TW of 17 pounds, there’s about 10 pounds of gas left, or little more than half a tank.

3. Install a gauge on the outside of the building. Options for external propane tank gauges include:

- Installed between the gas line from the grill and the tank’s cut-off valve, inline pressure gauges measure pressures to determine how full the tank is.
- Analog propane scales resemble luggage scales and are pre-programmed to account for your tank’s TW.
- A digital display of remaining cook time and gas fill percentage is provided by digital propane tank scales. Some even have apps for smart phones.

Choose a gauge that you like (they’re available at your local hardware shop and on Amazon) and try it out!

Don’t let your propane cylinder burn you.

Before your next summer party, use these ways to figure out how much gas is left in your tank. Don’t panic if you run out of propane; simply visit one of our Connecticut showrooms for a propane cylinder refill!

## Is there a propane tank gauge?

Your propane tank has a gauge on it, regardless of its size, so you always know how much propane gas you have on hand and when it’s time for a propane delivery. But keep in mind that reading propane tank gauges is not the same as checking your car’s gas gauge.

## When a 20-pound propane tank is full, how much does it weigh?

The most popular size of BBQ propane tank is 20 lb. It can also be used to fuel a number of propane heaters and even propane generators.

The dimensions of a 20-pound propane tank are 8 inches length and 4-inches wide. According to the 80 percent safety guideline, a 20 lb propane tank can hold a total of 16 lb of propane.

The empty 20-pound propane tank weighs around 13.5 pounds. Aluminum 20 pound propane cylinders are lighter than steel cylinders.

On average, a full 20-pound propane tank weighs 29.5 pounds. To determine the total, add the 16 pound of propane to the empty weight (13.5 pound) of the 20 pound propane tank.

Overall, a 20 pound propane tank has a lot of BTUs. What is the precise number of BTUs in it?

344,470 BTUs are contained in a 20 pound propane tank. That’s enough to keep a 10,000 BTU/h heater running for several days (34.4 hours, to be exact).

## What is the weight of a full propane tank?

The collar also has a month and year on it, showing when the tank was constructed. For 20-pound propane tanks, you have 12 years from the date of manufacture to re-certify the tank with a new date stamped on it. Re-certification simply adds 5 years to the time between re-certifications. Almost always, the cost and hassle of re-certifying outweighs the cost of a new tank.

## What’s the lowest I can go with my propane tank?

Allowing your propane tank gauge to dip below 20% is not only inconvenient for you and your family, but it can also be dangerous. It is designed to create a faint propane smell as your propane supply falls low.

## How accurate is the propane tank gauge?

A gauge may be found on almost every Ressler Propane tank. To learn how to read the propane tank on your property, look at the photographs below. The majority of propane tank gauges range from 5% to 90% full. Multiply the outage reading by the tank’s capacity to find out how much gas is left in the tank.

A 500 gallon propane tank with a 40% remaining capacity = 500 x 0.4 = 200 gallons.

These values are estimates and should only be used to estimate the number of gallons in the tank.

## In a 20-pound propane tank, how much propane is there?

Propane grills, generators, patio heaters, and other outdoor equipment are examples of its use. Find a location near you to buy or exchange a 20-pound tank. Grill cylinders are 20-pound propane tanks that store 4.6 gallons of propane when fully charged.

## How long would a 20-pound gas tank keep you going?

Grills, water heaters, and fireplaces all use small, portable propane tanks, often known as DOT tanks. They can weigh anywhere from 20 to 100 pounds. Its lifespan is determined by the size of your grill and how frequently you use your heater or fireplace.

A medium-sized grill on high heat will use about two pounds of fuel per meal as a rule of thumb. On a medium grill, a 20lb propane tank will give 18-20 hours of cooking time if you follow this rule. In as little as 10 hours, a larger barbecue can burn through 20 pounds of propane.
