DEVICE FOR MEASURING PARAMETERS OF LIQUID MEDIA IN PIPELINE Russian patent published in 2017 - IPC G01N9/26 G01F1/86 

FIELD: measuring equipment.

SUBSTANCE: device contains a measuring column made in the form of two coaxial vertical pipes installed with an annular gap - with an outer pipe and an inner pipe, a pressure difference transducer installed at the top of the measuring column, two pressure difference transducers installed at the bottom of the measuring column, a pressure sensor and a temperature sensor for the measured liquid, impulse tubes with "reference" liquid, and a recording unit. The measuring column is equipped with an additional pressure difference transducer, which pressure tapoff points are spaced apart in height L, and the pressure tapoff points of the pressure difference transducers installed at the bottom of the measuring column are spaced apart in height ΔH. The differential pressure transducer, the pressure and temperature sensor of the measured liquid are placed on the outer vertical tube of the measuring column and connected to the recording unit which is equipped with a program for calculating parameters such as density, speed, flow, pressure, and viscosity of the measured liquid in accordance with the attached formulas.

EFFECT: increased accuracy of measuring the density of the measured liquid and expanded functionality of the device.
