Type definition

The IfcFlowInstrumentTypeEnum defines the range of different types of flow instrument that can be specified.

HISTORY New enumeration in IFC2x2.

Enumeration definition

Constant	Description
PRESSUREGAUGE	A device that reads and displays a pressure value at a point or the pressure difference between two points.
THERMOMETER	A device that reads and displays a temperature value at a point.
AMMETER	A device that reads and displays the current flow in a circuit.
FREQUENCYMETER	A device that reads and displays the electrical frequency of an alternating current circuit.
POWERFACTORMETER	A device that reads and displays the power factor of an electrical circuit.
PHASEANGLEMETER	A device that reads and displays the phase angle of a phase in a polyphase electrical circuit.
VOLTMETER_PEAK	A device that reads and displays the peak voltage in an electrical circuit.
VOLTMETER_RMS	A device that reads and displays the RMS (mean) voltage in an electrical circuit.
COMBINED	A device that reads and displays the value of multiple properties of a system at a point, or displays the difference in the value of a property between two points.
VOLTMETER	A device that measures and displays the voltage in a circuit.
USERDEFINED	User-defined type.
NOTDEFINED	Undefined type.
