Axiomatization Decision Log
1
Identity-Giving Function
Function class
FlowMeasurementFunction
⊑ DesignedFunction
Realized in
FlowMeasurementProcess
⊑ PlannedProcess
Reusing the existing FlowMeasurementFunction from the already-enriched 'flow meter' class. A Coriolis mass flow meter shares the same identity-giving function as other flow meters - to measure flow characteristics of fluids.
2
Genus Determination
FlowMeter
The parent_candidates list includes 'flow meter' which is already enriched in our ontology. This is the most specific appropriate superclass. Coriolis mass flow meter is explicitly defined as a specialized type of mass flow meter, and flow meter is the broader category that encompasses both volumetric and mass flow measurement devices.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These parts constitute the essential Coriolis measurement mechanism: oscillating tubes, driving mechanism, force detection, and signal processing.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— continuous flow through measurement tubes
Outputs (O)
PortionOfFluid
— same fluid with measured mass flow characteristics
FlowMeasurementResult
— proportional to actual mass flow rate
Transformation (T)
measurement transduction - fluid flow characteristics converted to electrical signal without altering fluid composition
Coriolis meters provide inline measurement without flow restriction or fluid modification, outputting the measured fluid plus measurement signal
5
Axiom Mode Decision
Necessary conditions only
— modelled as a primitive universal
(⊑, SubClassOf). Identity is grounded in designed
function and cannot be reduced to a property checklist.
Using necessary conditions for this constructive type. Under the Open World Assumption, defining sufficient conditions based on Coriolis principle usage could lead to false positives where other devices using Coriolis forces (like gyroscopes or accelerometers) might be incorrectly classified as flow meters. The structural differentia provides necessary conditions that can be validated by domain experts.
Cross-Standard Observations
Both CFIHOS and POSC Caesar provide identical definitions focusing on the Coriolis principle for mass flow measurement. No conflicting interpretations observed across sources.
