Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
FlowSwitchingFunction ⊑ DesignedFunction
Realized in
FlowSwitchingProcess ⊑ PlannedProcess
The identity-giving function combines flow detection with switching action at preset flow rate thresholds. This differs from pure flow measurement (flow meter) or pure switching (generic switch) by the specific coupling of flow sensing with binary switching output.
2 Genus DeterminationDeterminação do Gênero
Instrumentbfo:Object (BFO_0000030)
Flow switch is fundamentally an instrumentation device that measures flow and provides control signals. While parent candidates include 'FLOW MEASURING INSTRUMENT' and 'PROCESS SWITCH', the most appropriate genus is 'Instrument' as it encompasses both measurement and switching instrumentation functions. The enriched classes show many instruments (transmitter, indicator, etc.) under this genus.
3 Differentia SpecificaDiferença Específica
∃bearerOf.FlowSwitchingFunction

Bears a function to switch electrical circuits based on detection of preset flow rate conditions.

The differentia is the specific FlowSwitchingFunction that combines flow detection with binary switching behavior. This distinguishes it from other flow instruments (meters, transmitters) that provide continuous signals, and from other switches that respond to different process variables.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts are universal - any flow switch implementation requires flow sensing, switching capability, and setpoint adjustment regardless of the specific technology used.
