How to measure a fuel tank?

An essential first step in figuring out a fuel tank's capacity and suitability for your diesel generator is to measure it. By taking accurate measurements, you may select the best gasoline tank for your requirements, avoid potential issues, and guarantee safe and effective operation. In this manual, we'll show you how to measure a fuel tank to ascertain its size and content.

Determine the type of fuel tank. 

To determine the type of fuel tank, you need to inspect its shape and characteristics. The most common fuel tank shapes are rectangular, cylindrical, and irregular.

1. Four straight sides and 90-degree angles characterize rectangular tanks. They are often used for large fuel storage and have a straightforward method of measuring their volume.

2. Cylindrical tanks have circular cross-sections and are usually used for smaller fuel storage. They are easier to manufacture than rectangular tanks, and their volume is calculated using the formula πr^2h, where r is the radius and h is the height of the cylinder.

3. As the name implies, irregularly shaped tanks don't follow either rectangular or cylindrical shapes. It can be more difficult to gauge their volume due to their potential for having intricate curves and angles. These tanks can still be measured, though, by manually taking measurements and then calculating their volume.

It is essential to correctly identify the type of fuel tank you are working with, as this will impact the method you use to measure its volume.

Obtain the tank's dimensions. 

To obtain the tank's dimensions, you will need to measure specific parts. The following are the most commonly used dimensions for different types of fuel tanks:

1. Rectangular tanks: Measure the length (L), width (W), and height (H) of the tank. These measurements are essential for calculating the tank's volume using the formula L x W x H.

2. Cylindrical tanks: Measure the diameter (D) and height (H) of the cylinder. The diameter calculates the radius (r) by dividing it by 2. The radius and height are then used to calculate the volume using the formula πr^2h.

3. Irregularly shaped tanks: For irregularly shaped tanks, you will need to take manual measurements of various parts of the tank to determine its volume. You can use a measuring tape, laser measurer, or other similar tools to take accurate measurements.

It is crucial to measure the dimensions accurately to calculate the fuel tank's volume. Some tanks may have different shapes on different sides, so you may need to take multiple measurements from different angles to get a complete picture of the tank's dimensions.

Calculate the tank's volume using appropriate formulas. 

To calculate the volume of a tank, you need to know the shape of the tank. There are three main shapes: rectangular, cylindrical, and irregular.

1. Rectangular: To calculate the volume of a rectangular tank, use the formula V = l x w x h, where l is the tank's length, w is its width, and h is its height.

2. The formula is V = r2h, where V is the volume, r is the radius, and h is the height. The mathematical constant, pi, can be used to calculate the volume of a cylindrical tank (approximately equal to 3.14).

3. Irregular: For an irregularly shaped tank, you must take manual measurements and use mathematical calculations to determine its volume. You can do this by dividing the tank into smaller, regular shapes (such as cylinders or rectangular prisms) and calculating the volume of each one. Then add up the volumes of each shape to find the tank's total volume.

It's important to note that these formulas assume that the tank is empty and doesn't consider any internal structures that might affect the volume. Additionally, these formulas are only accurate if the measurements are taken correctly. Read What causes the generator to consume more fuel? Here. 

Determine the fuel level using a measuring stick or gauge. 

To determine the fuel level in a tank, you can use either a measuring stick or a gauge.

1. Measuring Stick: A measuring stick is a long, thin rod marked with increments of volume or length. To use a measuring stick, insert it into the tank until it touches the bottom. Then, measure the distance from the top of the liquid to the mark on the measuring stick that is closest to the surface of the liquid. This measurement is the fuel level in the tank.

2. Gauge: A gauge is a device attached to the tank and measures the level of liquid inside. There are two types of gauges: mechanical and electronic. Mechanical gauges use a float that rises and falls with the level of the liquid. The float's position is indicated on a dial or a graduated scale. Electronic gauges use sensors to measure the level of the liquid and display the results on a digital readout.

It's important to periodically check the fuel level in a tank to ensure enough fuel for the intended use and to prevent the tank from becoming overfilled or running out of fuel. Additionally, checking the fuel level helps to identify any leaks or other issues with the tank. Read Does running out of diesel damage the engine? Here

Convert the fuel level measurement to volume. 

To convert fuel level measurement to volume, you first need to know the size of the fuel tank. With that information, you can calculate the volume of fuel in the tank by multiplying the height of the fuel in the tank by the cross-sectional area of the tank.

1 inch of fuel in a tank can be converted to gallons or liters by using the following conversion factors:

• 1 US gallon = 231 cubic inches

• 1 liter = 61.0237 cubic inches

For example, if the fuel tank has a cross-sectional area of 10 square inches and the fuel height is 5 inches, the fuel volume in the tank would be 50 cubic inches.

To convert cubic inches to gallons, divide by 231. So, 50 cubic inches would equal approximately 0.21587 gallons.

To convert cubic inches to liters, divide by 61.0237. So, 50 cubic inches would equal approximately 0.81685 liters.

Please note that these conversion factors are only approximations and may not be accurate for all fuel tanks. It is always recommended to consult the manufacturer's specifications for exact conversion values. Read here, How to start a diesel engine that runs out of fuel?

Subtract the current fuel volume from the tank's overall volume to find the space. 

To find the space in a fuel tank, subtract the current fuel volume from the overall volume of the tank. It will give you the volume of air or space in the tank.

The overall volume of a fuel tank can be calculated by using its dimensions and shape. If the tank is a simple rectangular shape, you can calculate its volume by multiplying its length, width, and height. If the tank is more complex in shape, you will need to use calculus or specialized software to find its volume.

Once you know the overall volume of the tank, you can find the current fuel volume by converting the fuel level measurement to volume, as explained in the previous response. Then, subtract the current fuel volume from the overall volume of the tank to find the volume of space in the tank.

It's important to monitor the fuel volume and space in a fuel tank to ensure safe and efficient operation. By knowing the amount of space in the tank, you can prevent overfilling and the associated risks, such as fuel spilling or causing damage to the tank. Additionally, you can use the space to help calculate the fuel's temperature and pressure, which are important factors in determining the fuel's performance and efficiency.

In conclusion, finding the space in a fuel tank is a simple calculation that requires knowledge of the tank's overall volume and the current fuel volume. Subtracting the current fuel volume from the overall volume will give you the volume of space in the tank. This information can be used to help ensure the safe and efficient operation of the fuel system. See here, Why Does Diesel Mix With Engine Oil On My Diesel Engine Generator?
