Standards Traceable Verification of Vibratory Meters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vibratory meter verification systems lack standards traceability, making it difficult to compare measurements accurately across different meters, as baseline stiffness and calibration values are not traceable to measurement standards.
Innovation Solution
A system and method for standards traceable verification of vibratory meters, which involves determining a baseline meter verification value and establishing a relationship between this value and a calibration value traceable to a measurement standard, using equations to relate physical properties like stiffness and mass to calibration factors, ensuring comparisons are made with standards traceable values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If baseline meter verification values are used without standards traceability, then meter verification can be performed, but accurate comparisons across different meters cannot be made
Solution Approach 1:
The patent introduces a calibration value as an intermediary element that bridges the baseline meter verification value and the measurement standard. The calibration value, which is traceable to measurement standards, is used to convert or relate the baseline verification value to standards-traceable units, enabling accurate comparisons while maintaining the verification process
Solution Approach 2:
The patent changes the parameter status of the baseline meter verification value from being a standalone value to being related to a calibration value that has standards traceability. This parameter change enables the verification value to be expressed in terms of measurement standards, resolving the contradiction between performing verification and achieving accurate, traceable comparisons
2Reliability
If baseline stiffness values are used for verification, then sensor assembly changes can be detected, but the values are not traceable to measurement standards
Solution Approach 1:
The calibration value serves as an intermediary that connects the baseline stiffness value to measurement standards. By establishing a relationship between the baseline stiffness and the calibration value (which is traceable to standards), the patent enables both reliable verification of sensor changes and standards traceability simultaneously
3Productivity
If meter verification is performed without standards traceability, then verification can be conducted, but comparisons between different flow meters are not reliable
Solution Approach 1:
The calibration value, being traceable to measurement standards, provides a universal reference that can be applied across different vibratory meters and flow meters. This universal standard enables accurate comparisons between different meters while maintaining the verification capability for each individual meter
