DENSITY GAUGE FOR LIQUID OR GASEOUS MEDIUMS Russian patent published in 2009 - IPC G01N9/26 

FIELD: physics, measuring.

SUBSTANCE: use: for measuring of density of liquid or gaseous mediums. Density gauge for liquid or gaseous mediums, contains the loop-type pipe of equal section consisting of ascending, horizontal and descending branches, three pressure selectors mounted accordingly on ascending, horizontal and descending branches of the loop-type pipe, two data units of a difference of pressures, the data unit of terrain clearance pressure of a working environment, a working environment temperature sensing device, pulsing tubes with the "reference" fluid, perceiving pressure of a working environment immediately contact method, and the registering block, thus it is supplied by a temperature sensing device of a "reference" fluid, and additional pressure selector on the case of the thermometer of a temperature sensing device of a "reference" fluid, thus the pressure selectors mounted on ascending, descending branches of the loop-type pipe and the pressure selector, disposed on the case of the thermometer of a temperature sensing device of a "reference" fluid, are located at one level in the inferior part of a loop, And the pressure selector, mounted on an ascending branch, pressure transmits to the data unit of a difference of pressures in its minus cabinet, the pressure selector, located on a horizontal branch, transmits pressure in positive cabinets of data units of a difference of pressures, the pressure selector, mounted on a descending branch, transmits pressure in the minus cabinet of other data unit of a difference of pressures, thus data units of a difference of pressures, the thermometer of a temperature sensing device of a "reference" fluid, the data unit of terrain clearance pressure of a working environment and a working environment temperature sensing device are related to the registering block.

EFFECT: increase of measurement accuracy of density of liquid or gaseous mediums.
