The liquid propane volume in any LP Gas container is directly related to its temperature.Honda EU2200i Propane Conversion Kit - DIY Install for Honda Generator
In fact, the volume of any liquid in any container is directly related to its temperature. Propane volume rises as temperature rises and falls as temperature falls. Being temperature dependent, propane becomes more dense as temperature falls and expands as temperature increases. This is extremely important to remember when understanding propane temperature and volume and the relationship between the two.
Propane is stored and delivered as a liquid. In comparison to other liquids regarding temperature and volume, it is no different. The volume of any liquid will rise and fall dependent upon temperature. To understand what's going on with regard to differing tank gauge readings in extreme temperatures hot or coldwe need to first explain basic principles that affect the liquid propane volume. Although the propane volume has decreased, the amount of propane has not decreased, it has simply become more compact dense.
The amount of usable energy has not decreased. If the temperature were to rise by the same respective amount, the gauge would indicate a higher volume of propane but there would still be pounds of propane in the tank. As temperatures fall, liquids become more dense and compact.
As temperatures rise, liquids become less dense and expand. Propane is a liquid and is subject to the same rules of mother nature. Propane users can become quite confused during periods of cold weather following a gas delivery because their propane tank gauge may read less than what they expect it to read. Cold weather often brings confusion and frustration for propane customers concerning perceived propane volume and the actual amount of propane delivered but the reality is this; When a propane delivery is made during cold temperatures, the tank gauge will indicate less propane delivered based on the beginning and ending gauge readings but the actual amount of propane delivered, according to a properly calibrated truck meter is what was truly pumped into the tank during the delivery.
We could explore gauge readings and propane volume correction in hot weather and high temperatures but nobody seems to be concerned when their tank gauge indicates that more propane was delivered than actually was. However, we will briefly explain below the propane truck's built in volume correction device, called a temperature compensator.
If temperature compensation was not taken into account, propane companies would be either getting more propane than they paid for less, depending on the temperature. Considering volumes in excess of 10, gallons are being delivered into a bulk storage plant, it's assured that propane companies certify volume correction factors are in place. The same is true on the consumer side but state and federal governments regulate measurement that is protective of the consumer.
Propane delivery trucks all have meters that measure the amount of propane pumped into consumer tanks. These meters include a volume correction device known as an automatic temperature compensator.
The temperature compensator takes into account the temperature of the liquid propane running through the meter and automatically adjusts to correctly deliver the amount of propane that the consumer ordered. By law, these devices are required to be re-calibrated and are adjusted based on the temperature of the liquid at the time of calibration.
When a delivery of propane is made to your home or business, know that the amount you paid for is the amount you are actually getting.Deciding to convert to propane from natural gas can be a tough decision as there are pros and cons to both fuel sources. Both fuels are efficient, clean-burning sources of consistent heat. Cost differences can vary based on your location and normal shifts in natural resource prices. However, there are a few ways that propane comes out ahead.
Each unit of propane contains twice as much energy per unit as natural gas. Therefore, you only need about half as much propane versus natural gas to achieve the same level of heating. When comparing energy costs, it is important to be aware that you will need about half the amount of propane to heat to the same extent as natural gas. Therefore, the cost efficiency is roughly equal when the propane price for the same volume is about double the natural gas price.
If the propane price is less than double, propane is more cost effective and if propane costs more than double natural gas, natural gas is more efficient. Even when prices fluctuate, propane has one big advantage. With propane, you have a tank and can try to time your purchases to when prices are low and find the best providers to fill it.
With natural gas, you're locked into the pricing of the utility company that owns your gas lines. To learn more about how to compare costs and why you should make the switch to propane, take a look at our homeowner's guide to natural gas vs.
You'll need to install a tank big enough to hold several thousand cubic feet of propane on your property. Many people prefer to bury it under their yard to preserve their home's appearance.
This may require digging up your grass, but luckily this will not be a permanent nuisance and your beautiful yard should grow back fully in the warmer months. Even though propane and natural gas are both fossil fuels that burn similarly, you need to convert your appliances when you make the switch. Because they have different densities and amounts of energy, you must switch out the valves and switches to properly control the flow when switching from one to the other. Most, but not all, appliances can be converted from natural gas to propane.
The biggest sticking point is that natural gas is kept at a lower pressure, and some appliances can't handle the higher pressure of propane even with adjustments.
What to Know About Natural Gas to Propane Conversion
It is important to consult a professional when considering making the switch from natural gas to propane as the work involved is highly technical and can be dangerous if the person doing the work does not have the required experience.
Ideally, when you buy a new appliance, you should make sure it comes with a conversion kit in case you decide to convert between propane and natural gas in the future. For older appliances where you don't have a kit, you can buy one separately. Be sure to read the instructions for both the kit and your appliance to ensure you can safely use the kit. Most stoves come set up ready for natural gas because it is most commonly used for indoor cooking.
If you want to switch to propane, you'll probably need to convert a gas stove. The biggest switch needed for a stovetop is switching to burners with smaller orifices so that less propane comes out.
Propane Volume and Temperature Correction
Remember that propane has more heat energy, so you need less to cook your food. Because of the dangers of gas leaks, we recommend leaving this part of the job to a professional like Petro Home Services.

Propane volume increases as temperature increases and decreases as temperature decreases. We will explain propane volume and temperature correction.
We store and deliver propane as a liquid. In comparison to temperature and volume of other liquids, it is not any different. The volume of any liquid will increase and decrease dependent upon temperature. In addition, the following are also true:. While the propane volume has dropped, the amount of propane has not decreases. It has simply become more compact, which means the amount of usable energy has not decreased. If the temperature were to increase by the same respective amount, the gauge would indicate a higher volume of propane.
However, there would still be pounds of propane in the tank. As temperature decreases, liquids become more dense. Therefore, as temperature increases, liquids become less dense and expand. Propane is a liquid and is subject to the same rules of mother nature. During cold weather following a gas delivery, your propane tank gauge may read less than what you might expect. This would be assuming the tank was empty at the time of delivery. Cold weather can often bring confusion and frustration for our propane customers concerning perceived propane volume and the actual amount of propane delivered.

A compression ratio tells you how many cubic meters a liter of liquid yields when released as gas. Propane, in particular, has a very high compression ratio and small amounts of liquid renders a high volume of gas. If you're used to dealing with gallons and feet, you need to do some conversion, as scientific measurements of this kind are usually given in metric.
Take the number of gallons of propane that you want to find the conversion factor. Convert that number to liters by multiplying it by 3. Multiply the metric measure of liquid by the conversion ratio for propane. Since propane has a conversion ratio ofone unit of liquid propane yields units of vaporous propane: Divide the uncompressed measure of propane by 1, So, multiply your metric volume measure by 3.
Hence, 30 gallons of propane fills 1, You can get an idea of how large the volume is by comparing it to the volume of a balloon. A standard party balloon has a volume of about 0.

Propane is a gas at standard conditions. The phase diagram for propane shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the propane boiling point with changes in pressure.
It also shows the saturation pressure with changes in temperature. At the critical point there is no change of state when pressure is increased or if heat is added. The triple point of a substance is the temperature and pressure at which the three phases gas, liquid, and solid of that substance coexist in thermodynamic equilibrium. Back to top.

Volume of Propane
This article answers common questions about how to calculate various measures of natural gas and propane, including conversion between cubic feet and gallons and BTUs. General safety warning: improper installation and even improper inspection and testing methods involving natural or "LP" gas can involve dangerous conditions and risk fire or explosion. If you smell gas you should leave the building immediately and should do so without doing anything that could create a spark such as operating a light switch or telephone.
The text provided here is a working draft and may be incomplete or inaccurate. On by mod re: how to convert cubic feet gas meter readings to gallons of propane. Teri I didn't find a detailed specification for the American AC LP gas meter, but from a look at its data tag right on the propane meter we see that it is a temperature-compensated meter that reads gas usage in cubic feet at 60 degF.
The sticker reading Temp. Do I then multiply the 48 X 7. My meter has a red sticker on it that says "Temp. I'd love any help! Best bet, let's state the question so an engineer can't duck it, then look on your smoker to identify the brand and model, then ask the manfuacutrer to send you the right orifice parts. Somethiing like: Can you provide me with the proper orifices in a conversion kit to convert my BrandX ModelY smoker made by you from LP gas to Natural gas?
Or from Natural gas to LP gas? On by mod re: Can a Hi, Thanks for the response, My valve does say I assume this valve will work on anything up to I don't know, Terry. Look closely at the gas control valve labeling or find its specification sheet. The kBTUH number may be a maximum that the valve accomodates; the spec sheet will give an operating range of btus. On by mod re: if we use cubic meters liters of gas vapor per day at 50c per liter How much is this per cubic meter M 3 of Vapor.
Chris, Thanks for the excellent question. Multiply Liters of LPG x 0. Other sources give the conversion number as 3. Why the confusion of multiple conversion numbers? Because the ambient temperature affects the volume of gas vapor that you'll get from a liter of liquid LPG.I have some woodworking I need to do, and my little woodshop is in my garage. Unfortunately, Minnesota is quite cold at the moment and working in the garage is not comfortable.
After decades of working out in the cold, I decided it is time to get a small heater to make things a bit more comfortable. I have used propane for years with my barbecue grill, but I have never used it for heating a space. While at university many decades ago, I worked in construction, and we used propane heaters to make working in partially-completed homes more comfortable in the winter.
I went to Home Depot and purchased the propane heater shown in Figure 1. This should provide enough heat to warm my garage so I can work in it comfortably. I like the fact that it is small, and I can easily store it during the summer.
I have too much stuff to manage as it is, and I do not need any more big stuff. Figure 2: Propane Tank Construction Source. Appendix B provides some information on the how the pressure in a propane tank varies with temperature. I found the following statement in this document. Figure 5 shows how I confirmed this statement using the propane density versus temperature relationship I compute in Appendix A — I thought it was a bit messy to include in the main post.
In Figure 5, I derive a rate of 1. The Wikipedia lists 1. My value is in the ballpark, but not as close as I like to be. Figure 6 shows my estimate for the amount of heating time I should expect from a 20 lb tank of propane — The energy density of propane comes from this source. I like to understand a bit about any product I use. This analysis gave me a bit of insight into how propane is used for space heating.
