Modelica.Thermal.FluidHeatFlow.Sensors

Ideal sensors to measure port properties

Information

This package contains sensors:

• PressureSensor: absolute pressure
• TemperatureSensor: absolute temperature (Kelvin)
• RelPressureSensor: pressure drop between flowPort_a and flowPort_b
• RelTemperatureSensor: temperature difference between flowPort_a and flowPort_b
• MassFlowSensor: measures mass flow rate
• VolumeFlowSensor: measures volume flow rate
• EnthalpyFlowSensor: measures enthalpy flow rate

Some of the sensors do not need access to medium properties for measuring, but it is necessary to define the medium in the connector (check of connections). Thermodynamic equations are defined in partial models (package BaseClasses). All sensors are considered massless, they do not change mass flow or enthalpy flow.

Pressure difference sensor

Information

The RelPressureSensor measures the pressure drop between flowPort_a and flowPort_b.

Thermodynamic equations are defined by Interfaces.RelativeSensorBase.

Extends from FluidHeatFlow.Interfaces.RelativeSensorBase (Partial model of relative sensor without signal output).

Temperature difference sensor

Information

The RelTemperatureSensor measures the temperature difference between flowPort_a and flowPort_b.

Thermodynamic equations are defined by Interfaces.RelativeSensorBase.

Note: Connected flowPorts have the same temperature (mixing temperature)! Since mixing my occur, the outlet temperature of a component may be different from the connector's temperature. Outlet temperature is defined by variable T of the corresponding component.
