Flow Conditioner With Integral Pressure Taps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurate fluid flow rate measurements in pipelines are hindered by distorted flow profiles caused by elbows, tees, and valves, making it difficult to achieve consistent and repeatable measurements without lengthy straight pipes, which are impractical and costly.
Innovation Solution
A flow conditioner with integral pressure taps that allow for easy measurement of pressure drop without additional equipment, providing a standardized layout for consistent readings and eliminating the need for pipe wall tapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If long lengths of straight pipe are used to achieve fully developed flow profile, then measurement accuracy is improved, but installation cost and space requirements worsen
Solution Approach 1:
The patent divides the flow conditioning function into discrete elements (perforations, raised features, recesses) distributed across a compact plate structure, replacing the need for long continuous straight pipe with segmented flow-conditioning elements that achieve profile development in a short distance
Solution Approach 2:
The flow conditioner plate acts as an intermediary device between the distorted flow source (elbows, valves) and the flow meter, using its structured surface features to gradually reshape the flow profile without requiring extended pipe length
2Measurement precision
If separate orifice fittings are used to measure pressure drop, then pressure measurement capability is achieved, but device complexity and installation cost worsen
Solution Approach 1:
The patent combines the pressure measurement function directly into the flow conditioner plate by integrating pressure taps into the plate structure itself, eliminating the need for separate orifice fittings and reducing overall device complexity
Solution Approach 2:
The flow conditioner plate serves multiple functions simultaneously: it conditions the flow profile, measures pressure drop through integrated taps, and provides a mounting structure, replacing what would traditionally require multiple separate components
3Measurement precision
If pipe wall tapping is performed to install pressure measurement equipment, then pressure measurement is enabled, but installation difficulty and risk of damage worsen
Solution Approach 1:
The pressure measurement function is merged into the flow conditioner plate structure itself, with pressure taps formed as integral features of the plate, eliminating the need for separate pipe wall tapping operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate and repeatable fluid flow measurements by creating a fully developed flow profile and allowing pressure drop measurement directly on the flow conditioner, reducing costs and complexity.
Implementation Method 1
The perforations or holes in the flow conditioner cause the fluid flow to be redistributed such that it forms a fully developed flow profile
Implementation Method 2
measuring fluid pressure with at least one integral pressure tap of a flow conditioner
Data Source
AI summary
A flow conditioner includes a plate having a hole pattern and a flange surrounding the plate; and at least one pressure tap that is integral with the flow conditioner. The at least one pressure tap is on at least one of a first face of the flow conditioner, a second face of the flow conditioner, within a hole, or any combination thereof.
