Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FlowMeasurementFunction ⊑ DesignedFunction
Realized in
FlowMeasurementProcess ⊑ PlannedProcess
The identity-giving function is measuring flow and producing a proportional signal. This function is already established in the ontology as used by 'flow meter' and 'orifice plate', confirming it as the correct identity-giving function for flow measurement equipment.
2 Genus DeterminationDeterminação do Gênero
Instrumentbfo:Object (BFO_0000030)
Flow elements are measurement instruments that detect and produce signals proportional to flow. While 'detecting element' from CFIHOS is more specific, it's not in our enriched classes. 'Instrumentation And Control Equipment' from POSC is too broad. 'Instrument' is the most specific appropriate superclass that exists in our ontology, already enriched and used by other measurement devices.
3 Differentia SpecificaDiferença Específica
∃hasFunction.FlowMeasurementFunction

A flow element is distinguished from other instruments by having the specific function to measure flow rates and produce proportional signals.

The FlowMeasurementFunction is the minimal differentiating condition that distinguishes flow elements from all other types of instruments under the same genus. This aligns with both source definitions emphasizing flow measurement as the defining characteristic.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts represent the essential functional components present in all flow elements regardless of their specific measurement principle (Coriolis, electromagnetic, thermal, etc.).

TransformationTransformação
flow information extraction and signal generation without significant fluid alteration
Flow elements are inline measurement devices that extract flow information and convert it to a proportional signal while allowing the fluid to continue flowing with minimal disturbance.
