METHOD AND DEVICE FOR DETERMINING FLOW PRESSURE USING DENSITY INFORMATION Russian patent published in 2010 - IPC G01F1/84 G01F15/04 G01F15/06 G01L11/00

Abstract RU 2385449 C2

FIELD: physics.

SUBSTANCE: flow metre processor (508) is configured to determine pressure of fluid material based on measuring density and temperature of the fluid material flowing through a channel (502). Density of the fluid material is determined based on measuring movement of a the channel (508) which vibrates under the effect of an exciter (504) using sensors (506).

EFFECT: easy measurement of flow pressure with no requirement for a pressure transducer and additional electronic circuits.
