How to Check Your Propane Levels
Easy propane tracking tips for your home tank or portable cylinder.
If you’ve recently moved to a home with a propane tank, added propane-powered equipment or just want to know how much fuel is in your grill tank, understanding how to check your propane levels is essential. Happily, you don’t need to be a licensed propane technician to do this. Just follow these simple steps to check your fuel levels.
Plus, if you’re in Harrisburg or another city or town in Central or Southeastern Pennsylvania, Koppy’s Propane has services that make keeping track of your propane even easier.
Checking Propane Levels in a Grill Tank
If you’re using propane for grilling, you likely have a 20-pound propane cylinder. Here are a few convenient ways to keep an eye on how much fuel you have left to avoid mid-cookout surprises:
- Built-In Grill Scale. Many modern grills include a built-in propane scale. This feature uses your tank’s weight to determine how full it is. Check your grill’s manual to see if this option is available.
- Weigh Your Tank. No built-in scale? No problem. A basic home scale can work just as well. Start by locating the tare weight (TW) on your tank’s collar, which indicates the weight of an empty tank. Then, weigh the tank on a home scale and subtract the tare weight from the total. Finally, divide the remaining weight by the cylinder’s total water capacity, which is also listed in the collar as WC. The resulting number is your current fill percentage!
- The Hot Water Trick. This simple and efficient technique requires no special tools. Just pour hot water down the side of the tank and gently run your hand along its surface. The tank will feel warm where it’s empty and remain cool where propane is still present.
- External Tank Gauge. For frequent grillers, an external propane gauge is a worthwhile investment. These devices attach between the propane tank valve and the grill regulator, providing either analog or digital readings of how much gas remains. Some gauges even estimate how many cooking hours are left!
Checking Propane Levels in a Stationary Home Propane Tank
For larger stationary propane tanks used to heat homes or power appliances, monitoring fuel levels is just as straightforward.
Inside the small dome on top of your propane tank, you’ll find a gauge resembling a car’s speedometer, with numbers ranging from 5 to 95. These numbers reflect the percentage of propane in your tank. A simple glance at this dial tells you how full your tank is.
Generally speaking, it’s best to schedule a propane delivery once your tank hits about 30% to ensure you never run out of fuel.
