SENSOR OF THE PRESSURE OF LIQUID IN A RESERVOIR Russian patent published in 2007 - IPC G01L11/02 G01L23/06 

FIELD: the invention refers to measuring technique.

SUBSTANCE: the sensor of the pressure of liquid is divided by a transparent partition on the upper insulated and the low open compartments. Above the transparent partition in the upper insulated compartment a measuring device of displacement of the level of liquid is installed in the low open compartment filled with liquid at submersion into it of a body. The measuring device of displacement has a television camera and a ring source of light. The sensor of the pressure of liquid is simple in manufacturing, has high accuracy and may work in aggressive, highly explosive, radioactive and other spheres for example on oil storages, filling stations, in chemical and other industries.

EFFECT: simplification in manufacturing and high accuracy of measurements.
