DEVICE FOR MEASURING THE MASS PETROLEUM TANK In Trench

摘要

1. Apparatus for measuring the mass of oil in the tank trench, comprising a measuring system that measures a level, density, temperature and mass of the product in the reservoir, the device dynamically control error measurement and display device, the first input of the dynamic measurement error control device connected to the output of the measuring system, by which receives the parameters level, density, temperature, and mass of product in the reservoir, the second entry entered accuracy characteristics measuring means minutes and the calibration parameters of the reservoir, and an output connected to a display device in which when measuring the mass of product in the reservoir are indicated by weight and the amount of error of measurement of weight, the minimum allowable level when the product is stored and a minimum level of change in the reception and product leave ensuring compliance largest measurement error, characterized in that the measuring system incorporated magnetostrictive sensors control the height of the vessel with movable elements with magnets, movable e elements with magnets attached to the roof trench reservoir from the output of the measuring system on the third auxiliary input device dynamically control the measurement error parameters height trench reservoir fed, which are processed with the calibration characteristics trench reservoir and the level of oil therein, when changing the height of the trench tank carried correction level measurements and weight of oil stored in the tank trench on the display device displays
