The MVS Tank calibration system is a Metricon patent. It is an automatic and fully equipped mobile workshop with the ability to measure barrels and tanks with a capacity from 0.5 to 100m3.
The tank calibration method is based on three separate systems that work in parallel, the Dosing System, the Level Measurement System and the Control and Recording System. Measuring liquid – water – is channeled from a tank installed in the MVS (with a capacity of about 1m3) to the Dispensing System device. The transferred quantity, doses of approximately 100L, is weighed by high-precision load cells – gravimetric method – and it is channeled into the volumetric tank. Proceeding to the second weighing in the Dispensing System device in order to measure the liquid residues which remained inside the device and to accurately determine the quantity that is finally channeled into the volumetric tank. Inside the tank, the level measuring device consisting of electronic sensors measures and records the level digitally. The process is repeated until the tank is filled at a rate of 5m3/h. During tank drops, all factors that contribute to and affect the tank calibration results temperature in the tank, temperature in the Dosing System, environmental conditions, and liquid density are measured and recorded. Having completed the tank calibration process, the data are sent to the Laboratory where they are evaluated, analyzed and the volumetric tables are created in the required format.
The procedure mentioned above is based on recognized methods. This fact combined with the use of calibrated equipment gives the possibility of providing results of accuracy depending on the capacity of the tank.
