.AixLib.Utilities.MassTransfer.MassFlowSensor .AixLib.Utilities.MassTransfer.MassFlowSensorThis model is capable of monitoring the mass flow rate flowing through this component. The sensed value of mass flow rate is the amount that passes through this sensor while keeping the partial pressure drop across the sensor zero. This is an ideal model so it does not absorb any mass and it has no direct effect on the mass transfer response of a system it is included in. The output signal is positive, if the mass flows from port_a to port_b.
