NON-INTRUSIVE PROCESS FLUID PRESSURE MEASUREMENT SYSTEM Russian patent published in 2022 - IPC G01L7/02 

FIELD: machine building.

SUBSTANCE: invention relates to devices for measuring pressure of process fluid in a pipeline. System for non-intrusive measurement of process fluid pressure in a process fluid pipeline, comprising: measuring bracket made with possibility of connection to external surface of pipeline for process fluid medium, wherein the measuring bracket forms a variable gap based on the deformation of the process fluid pipeline in response to the process fluid pressure therein; a gap measurement system connected to the measurement bracket and configured to provide an electrical signal based on the variable gap measurement; and a controller connected to the gap measurement system and configured to calculate and provide a process fluid pressure based on an electrical signal and information relative to the process fluid pipeline, wherein the process fluid pipeline information includes the process fluid pipeline wall thickness.

EFFECT: high accuracy of measuring pressure of a process fluid.
