1 Identity-Giving FunctionFunção Identitária
Function class
FlowSignalTransmissionFunction
⊑ SignalTransmissionFunction
Realized in
FlowSignalTransmissionProcess
⊑ SignalTransmissionProcess
The identity-giving function is the transmission of standardized output signals proportional to flow measurements. This is a specialization of general SignalTransmissionFunction that specifically handles flow process variables. All definitions emphasize the conversion/transmission of flow measurement to standardized output signals.
2 Genus DeterminationDeterminação do Gênero
transmitterbfo:Object (BFO_0000030)
Based on parent_candidates, 'transmitter' is the most specific appropriate superclass and is already enriched in our ontology with SignalTransmissionFunction. Flow transmitter is clearly a specialized type of transmitter that focuses on flow process variables. The ISO 15926 definition explicitly states it's a PROCESS VARIABLE TRANSMITTER, and CFIHOS/POSC definitions describe it as a transmitter with flow-specific functionality.
3 Differentia SpecificaDiferença Específica
∃bearerOf.FlowSignalTransmissionFunction ⊓ ∃hasInput.FlowMeasurementFlow transmitter differs from other transmitters by specifically handling flow process variables and producing output signals proportional to flow measurements.
The differentia specializes the general SignalTransmissionFunction to FlowSignalTransmissionFunction and specifies that the input must be flow measurements. This is minimal and distinguishing - any transmitter that handles flow measurements is by definition a flow transmitter.
4 Necessary PartsPartes Necessárias
No necessary parts recorded.
These parts are universal to all flow transmitters - every instance needs a flow sensing capability and signal conditioning/transmission capability. Specific sensing technologies (differential pressure, electromagnetic, etc.) are differentia for subtypes.

TransformationTransformação
signal conversion and amplification - converts flow measurement to standardized electrical signal
Flow transmitters receive flow measurements from sensing elements and convert them to standardized output signals. They require electrical power for operation. The core transformation is measurement-to-signal conversion, not process fluid transformation.
Disjoint WithDisjunto com
PressureTransmitter TemperatureTransmitter LevelTransmitter
C2: PressureTransmitter, TemperatureTransmitter, LevelTransmitter. These transmitter types have incompatible input signatures - they handle different process variables (pressure, temperature, level vs. flow) and cannot simultaneously be flow transmitters and other process variable transmitters.
