DEVICE FOR MEASURING DENSITY AND LEVEL OF LIQUID Russian patent published in 2016 - IPC G01N9/26 G01F23/64 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment and can be applied to systems for measurement of liquid media, for example, in chemical, petroleum, and other industries, where accounting liquid quantity (weight, volume) is required, which is stored in tanks. Device for measuring density and level of liquid comprises differential pressure gauge, wherein positive chamber is connected to pipe immersed into controlled medium, and negative chamber is connected to free from liquid space of reservoir, two-float level sensor, measuring element thereof is installed within pipe, and pipe is made in form of bell with broadening in its lower part (hereinafter, bell). First float of level sensor covers bell outside, and second float is under bell in extended part of measuring element of level sensor. Measuring element of level sensor and bell are tightly connected at upper part of bell, at that, there is gap between them, which enables to transmit hydrodynamic pressure impact into positive chamber of differential pressure gauge that is tightly connected to bell.

EFFECT: technical result of this invention is simplification of design, providing efficient average density monitoring of liquid in reservoir using simple process of measurements.
