Avoid a run out: How to read the gauge on your propane tank
Reading a propane gauge can sometimes be confusing. Propane gauges only go up to 80%, which represents a full tank. The remaining 20% of capacity is left empty intentionally to allow for safe thermal expansion of the gas inside.
How to Read Your Propane Tank Gauge
1. Locate the gauge under the dome
Carefully open the protective dome on top of your propane tank. During Maine’s summer months, use caution when lifting the hood, as wasps and hornets frequently build nests inside tank domes.
2. Check the dial reading
Once the dome is open, look for the small round dial with visible numbers. If you have multiple propane tanks tied together, be sure to check the gauge on each individual tank.
- 80% Reading: Indicates a completely full tank (accounting for expansion space).
- 30%–32% Reading: Indicates it’s time to order a fuel delivery.
Order Fuel When Your Gauge Reads 30%
If you are on will-call delivery rather than automatic delivery, monitor your fuel levels regularly and request a delivery as soon as your gauge drops to 30%.
Running out of propane causes more than just an inconvenient cold home or loss of hot water. A loss of heat during freezing temperatures risks frozen, burst pipes that can cause costly water damage. Additionally, if a propane system completely runs out of gas, Maine state safety codes require a mandatory leak/pressure check before service can be legally restored.
Remote Tank Monitoring
To eliminate the risk of unexpected run-outs—especially for backup generator setups—you can enroll in a wireless tank monitoring service. Cellular tank monitors attached directly to your tank transmit automatic level updates directly to the dispatch team, ensuring timely refills before levels reach critical thresholds.
