Methods to have an accurate measurement of a fuel tank

In the matter of measurement, expertise is required on the part of the team to use innovative methods and technology to measure with precision and avoid making costly errors in the process to obtain accurate measurements.

Measurement accuracy can have a value impact because the data collected from the tank tells us how much inventory we can safely handle. Some methods, such as tank strapping, help calculate the volume of a tank.

This method can have inherent inaccuracies, so other means, such as sonar technology, are being explored to get more accurate measurements.

In the tank measurement business, experience matters. The team should be composed of individuals with extensive knowledge of the latest technologies and regulatory practices. They should also be familiar with the layout of different types of tanks to provide accurate measurements.

Technology such as 3D laser scanners can take tanks' measurements quickly and accurately. This type of technology is becoming more commonplace in the industry and can help to provide measures that are much more accurate than traditional methods.

Tank strapping

Use of accurate calibration tables

If you use a strapping tank table, tank chart and tank strapping charts, you may have a better alternative to obtaining accurate measurements with quality. The use of gauging systems has applications in vertical, horizontal, spherical, and fixed-roof tanks.

Tank calibration chart

You may have accurate calibration tables and tank calibration charts for reference; however, to obtain precise measurements, the use of 3D laser scanning is an option that offers the highest degree of accuracy.

The use of 3D laser scanning for calibration and measurement of a tank

To have correct measuring and tank calibration, we can use a solution with a precise and safe method, such as 3D laser scanning. There are concepts such as EODR (Electro Optical Distance Ranging) to obtain accurate measurements.

The application of this method of scanning and inspection can be used in vertical tanks and horizontal tanks.

When the volume of many tanks is calculated in the companies, the customers will benefit from having a precise count of what we can offer them in the quantity of our product such as crude oil or other hydrocarbons, in addition to knowing if the value of the company to be an industry leader.

This technology is precise and offers quality data that can be used as support to make decisions in the different business processes of the company.

Why realized tank calibration?

The main reason to perform a tank calibration is: To obtain the real volume of the contents of the tank since, over time, the shape of the latter may have been modified by corrosion, deposits or other factors. In many cases, it is required by the authorities that regulate the activity of the company. To minimize inventory management errors, reducing the costs associated with them. To have updated information for the financial statements of the company.

Benefits of having a correct measurement of a tank

The benefits of having an accurate tank measurement It is essential to have an exact measure of the contents of a fuel storage tank for the inventory management of a hydrocarbon depot since, with this information, the volumes handled can be planned, and the levels of risk inherent in the operation are minimized. Inventory management with precision will have a direct impact on the financial statements of the company.

The main benefits of having an accurate measure of the contents of a tank are:

  • To calculate the hydrocarbon volume that a company can handle safely.
  • To avoid costly errors in the inventory management.
  • To have updated and precise information for the financial statements.
  • To be able to plan the operations more efficiently.

Tank calibration with 3D laser scanning

We can use 3D laser technology to calibrate the tank and obtain precise volumes. Using laser scanners will allow us to have an updated three-dimensional tank model, with which we can make the appropriate calculations.

The great advantage of using this technology is that the scanning can be done from a safe distance without having to enter the tank, which minimizes the risks associated with the operation. In addition, the scanner generates a large amount of data that can be used to obtain an exact measure of the tank's contents and detect possible irregularities in its shape. This technology is, therefore, a safe, precise and efficient solution for tank calibration.

Why do I need to measure my tanks?

It is crucial to have the precise size of the storage tanks to minimize inventory deviations. It will also facilitate communication between the Operation and Maintenance Department and the Audit department by having verifiable information on the geometric variations of the tank that affect the actual storage.

What do we do?

We obtain the complete and accurate configuration of the current dimensions (not nominal) to produce a 3D model based on a laser scan. Then, we run a filling simulation to produce a capacity table that is very useful for operators to report current fuel volumes accurately.
