Tilt Sensor Validation for Inline Flow Transducer Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inline measuring devices with vibration-type transducers face challenges in accurately measuring physical parameters like mass flow, density, and viscosity, especially in inhomogeneous media, due to non-reproducible measurement signals and self-emptying issues, which are exacerbated by unsuitable installed positions.
Innovation Solution
A method and system that utilize a tilt sensor to determine the instantaneous inclination of the measuring transducer relative to a reference axis, providing real-time feedback on the suitability of the installed position, ensuring self-emptying capability and measurement accuracy by signaling allowable or unallowable deviations from predetermined reference values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the measuring transducer is installed at an unsuitable position, then self-emptying capability is compromised, but measurement accuracy deteriorates due to non-reproducible signals
Solution Approach 1:
The tilt sensor performs preliminary detection of the installed position during start-up before actual measurement begins. The method checks the inclination angle against predetermined reference values and only allows operation when the position is suitable, preventing measurement errors from occurring in the first place
Solution Approach 2:
The system continuously monitors the installed position using the tilt sensor and provides feedback signals when deviations from reference values are detected. This feedback mechanism allows real-time validation and correction of position-related measurement issues
2Measurement precision
If the measuring transducer operates in inhomogeneous media, then measurement signals become non-reproducible, but adding position validation increases system complexity
Solution Approach 1:
The tilt sensor acts as an intermediary device that independently validates the installed position without interfering with the actual measurement process. It provides position information that can be used to correct or validate measurements without requiring complex modifications to the existing measurement system
Solution Approach 2:
The patent replaces complex mechanical position adjustment mechanisms with an electronic tilt sensor-based validation system. Instead of requiring precise mechanical installation, the system uses electronic detection and software-based reference value comparison to ensure proper positioning
