DEVICE AND METHOD OF DETERMINING LIQUID CARGO WEIGHT Russian patent published in 2011 - IPC G05D9/00 G08B13/196 G01G19/04 

FIELD: physics.

SUBSTANCE: method of determining liquid cargo weight in railway tanks consists in measuring liquid cargo level by thermovision image of tank lateral surface and calculating cargo volume and weight. It differs from known methods in that, natural sheet or shipping documents for the tank are used to determine tank type, declared cargo type and weight. Tank lateral surface part thermovision fragment corresponding to filled tank section is used to determine filled cargo temperature, and liquid cargo weight is calculated with due allowance for declared type and specific weight at measured temperature and tank type. Tank is weighed to subtract empty tank weight from measured weight to determine actual weight of liquid cargo. Now, said weight is compared with declared weight to conclude on commercial safety of cargo.

EFFECT: higher validity of cargo commercial safety control.
