Research on Horizontal Tank Position Identification and Capacity Indicator Calibration

Abstract

The measure error brought by the tank position changing is a problem need resolving for the enterprises that engaged in oil storage and processing. The paper will establish the mathematical model for the capacity indicator calibration of the tank whose position has changed, that is to say the model will show the relation between the oil capacity and the oil height and the position parameter (the vertical tilt angle α and the horizontal deflection angle β).The method will take the typical tank whose main body is cylinder and both ends are spherical. By the Use of the tank modification in /out the oil in the process of actual test data, we can determine the deflection parameters based on the mathematical model. Then we can give the calibration value interval of 10cm.We can further use the actual test data to test the validity and the reliability of the method.
