Does Cold Temperature Affect the Level Gauge on a Propane Tank?
Propane is similar to most other kinds of materials in that it is affected by cold temperatures. The propane gas contracts as the temperature does down. That reduced level of gas inside the tank is reflected by the gauge that reflects the level on the tank. Often, this comes into play whenever a homeowner checks the gauge in cold conditions and sees the amount of the tank level before and after delivery. Depending upon the climate, the tank level might not rise as much as expected.

Propane Tank Level Gauge
The propane tanks guage will show what portion of the gas tank is still full. Tanks are usually not filled over 80% full because this would allow for the gas to expand during hotter days. Like for example, a 500 gallon tank, at a reading of 80% at normal temperatures reflects about 400 gallons of propane in the tank. This is about the amount that is able to be stored.

Normal Temperatures
The propane industry operates the popular website Propane 101, that considers the propane reference point to be an exterior temperature of 60 degrees. Like for example, if the gauge reads 50 percent of capacity on a day when the temperature is near 60 degrees, then a 500 gallon tank would contain approximately 250 gallons of propane. If the temperature that day is a lot lower than 60 degrees, the gauge will read lower. Also, if the temperature is much higher than 60 degrees, the gauge would actually read higher because the gas expanded.

Effect of Expansion and Contraction
The energy contained or amount of energy contained in a tank will not change when the gas either contracts or expands, based on the propane industry website. The amount of propane itself has not changed, but just the density of the gas has changed.

Cold-Weather Delivery
The homeowner who orders 100 gallons of propane will receive roughly 424 pounds of propane. With the delivery of 100 gallons, the homeowner with a 1000 gallon propane tank can expect the guage to go up by 10%. These numbers would be correct if the temperatures were close to 60 degrees at the time of delivery. If the delivery happened during colder weather, these chillier temperatures will cause a smaller increase reading on the propane gauge.
