DEVICE TO MEASURE MASS OF OIL PRODUCTS IN TRENCH RESERVOIR Russian patent published in 2014 - IPC G01F22/00 

FIELD: measurement equipment.

SUBSTANCE: to measure mass of oil products in a trench reservoir comprising a measurement system, which measures level, density, temperature and mass of product in the reservoir, there are magnetostrictive sensors of reservoir height control with movable elements and magnets introduced into the measurement system. Movable elements with magnets are attached to the roof of the trench reservoir, parameters of height of the trench reservoir that are processed with account of calibration characteristic of the trench reservoir and the oil product level in it arrive from the outlet of the measurement system to the third additional inlet of the device of dynamic control of measurement error. Whenever height of the trench reservoir changes, measurements of level and mass of the oil product stored in the trench reservoir are corrected.

EFFECT: possibility to correct measurements of level and mass of product in case of variation of geometric dimensions of a trench reservoir.
