MassFlowRate

Ideal sensor for mass flow rate

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This component monitors the mass flow rate flowing from port_a to port_b. The sensor is ideal, i.e., it does not influence the fluid.

Parameters (3)

allowFlowReversal

Value: system.allowFlowReversal

Type: Boolean

Description: = true to allow flow reversal, false restricts to design direction (port_a -> port_b)

m_flow_nominal

Value: system.m_flow_nominal

Type: MassFlowRate (kg/s)

Description: Nominal value of m_flow = port_a.m_flow

m_flow_small

Value: if system.use_eps_Re then system.eps_m_flow * m_flow_nominal else system.m_flow_small

Type: MassFlowRate (kg/s)

Description: Regularization for bi-directional flow in the region |m_flow| < m_flow_small (m_flow_small > 0 required)

Connectors (3)

port_a

Type: FluidPort_a

Description: Fluid connector a (positive design flow direction is from port_a to port_b)

port_b

Type: FluidPort_b

Description: Fluid connector b (positive design flow direction is from port_a to port_b)

m_flow

Type: RealOutput

Description: Mass flow rate from port_a to port_b

Components (1)
