Solution Overview
Problem
Magnetic-inductive flow meters (MIDs) in the beverage industry face challenges with dirt accumulation on horizontal surfaces, requiring increased cleaning effort and complicating the routing of additional fluid paths, which affects measurement accuracy and design complexity.
Innovation Solution
Integrating the electronics unit into a common housing with the coil body, allowing for a compact design that reduces dirty surfaces and enables easier integration of additional fluid channels, including gas pathways, within the flow meter housing, thereby improving cleanability and reducing external cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic unit is provided in a separate housing from the coil body, then the electronic components are protected from fluid exposure, but dirt accumulates on horizontal surfaces requiring increased cleaning effort
Solution Approach 1:
The patent combines the electronic unit and coil body into a single integrated housing, eliminating the separate housing arrangement. This merging reduces the number of horizontal surfaces where dirt can accumulate and simplifies the overall structure, making cleaning more efficient while still protecting electronic components through internal sealing and routing arrangements
2Adaptability or versatility
If additional fluid paths are routed around the coil body, then control air and return gas can be supplied, but the design complexity and routing effort increase considerably
Solution Approach 1:
The patent integrates additional fluid paths directly into the housing structure, merging the main fluid channel with control air and return gas pathways. This eliminates the need to route pipes around the coil body, reducing design complexity and routing effort while maintaining full versatility for supplying control air, return gas, and pre-charge gas
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously serves as the structural enclosure, the main fluid channel, and the pathway for control air and return gas. This universal design consolidates multiple functions into a single structure, reducing the number of separate components and routing requirements
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
The integrated design enhances the cleanability and compactness of the flow meter, simplifies the routing of fluid paths, and reduces the need for external cabling, leading to improved hygienic performance and reduced installation effort.
Implementation Method 1
magnetic-inductive flow meters (MIDs) are known. The MIDs used in the beverage industry are designed such that a coil is provided in a housing, enclosing a fluid channel through which the product to be measured flows. A further housing containing the coil is arranged or flanged to this housing containing the coil, and this second housing contains an electronic component that interacts with the coil. The electronic component is designed, for example, to acquire and evaluate measurement information provided by the coil, such as flow-dependent voltage or current values.
