“…The strapping method uses steel meter standards [4][5][6] and optical methods that use theodolite or total station standards [7][8][9][10] that are located in outside of the tank. For the inside of the tank, a comparison of the two methods above has been produced, but it is not stated which method is better [11]. Strapping method testing requires more time and more personnel compared to the optical method.…”

Vertical Cylinder Tank is used as a storage area or as a measuring tool. Liquids are used in the form of Fuel oil, Liquid Natural Gas, vegetable liquids, and other chemical liquids. The tank calibration results are in the form of a volume per height table that is used as a reference by Automatic Tank Gauging. There are two tank calibration methods, namely: the strapping method and the optical method. The process of measuring the inside or outside diameter of the tank becomes very important in the tank calibration process—the measurement of tank diameter by the strapping method using steel meters manually. At the same time, the optical method uses theodolite or total station. For tank diameters ≤ 5 m, the strapping method has smaller diameter measurement results with a difference of 0.7% compared to the optical method. In further research, a prototype can be developed that can accelerate the calibration process using the strapping method (for example, a vertical track measuring robot) or a low-cost prototype theodolite

“…Any inaccuracy can cause problems in the supply chain. The use of known methods [18,19] and controlled measuring instrument characteristics allows for a valid fuel quantity assessment process [20]. Different parties in the performed commercial transactions agree on the different measuring instruments and methods used in the workflow and the interpretation of possible measurement errors [15].…”

Analysis of Liquid Quantity Measurement in Loading/Unloading Processes in Cylindrical Tanks

Tanks, as instruments in oil and its product’s amount measurement system chain, must be regularly maintained and metrologically inspected, as they significantly contribute to measurement uncertainty. However, when measuring a change in the amount of stored material (i.e., transfer), the measurement uncertainty becomes highly dependent not only on the mass of the transaction but also on the initial liquid level in the tank. This paper provides modeling of the uncertainties of the measuring system, which involves tanks, oil, and its product loading/unloading processes. It is shown that the accuracy of volume/mass measurement depends not only on the tank calibration table but also on the accuracy of other measuring instruments used and on the level of the liquid at the moment of measurement. The relative uncertainty of the measurement of the change in product mass depends linearly on the tank fill level present at the time of the transaction but nonlinearly on the transaction mass quantity.

“…These calibration results are usually displayed in the form of table volume per height. Previous studies showed that the vertical cylinder tank was calibrated by two methods namely the Manual Strapping Method (MSM) [3] and Electro-optical distance ranging (EODR) [4]. Higher cost of EODR calibration than MSM [3].…”

“…Higher cost of EODR calibration than MSM [3]. However, EODR takes a much shorter time [4]. Considering this measuring time, another study showed that 3D laser scan technology provided a much shorter time than EODR [5].…”

The vertical cylinder tank can serve as a measuring tool and as a storage device. When the vertical cylinder tank is used as a measuring instrument, it needs to be calibrated. In this process, measuring the diameter of the vertical cylinder tank is the most important step. The diameter of the tank is divided into several parts, the first part is referred to as a reference, where the results of the reference measurement will be used in the measurement of other parts. To conduct this measurement, a prototype consisting of two sensors, namely, laser distance and rotary encoder, is build. The prototype was tested using five variations in standard tube diameters measured using a steel ruler. The results of this test produce an average correction of +0.17 mm with an error of 0.59%. Furthermore, the prototype is used to measure the diameter of the vertical cylinder tank, which is compared with the certificate of the results of tank measurements using a theodolite. Testing the prototype with a vertical cylindrical tank produces a correction of +8.73 mm with an error of 0.03%. This error value is within the error limit according to the OIML International Recommendation of R-071 for vertical tanks.
