This model outputs the flow velocity flowing from
port_a
to port_b
.
The sensor is ideal, i.e., it does not influence the fluid.
If the parameter tau
is non-zero, then the measured
density that is used to convert the mass flow rate into
volumetric flow rate is computed using a first order differential equation.
Setting tau=0
is not recommend. See
IBPSA.Fluid.Sensors.UsersGuide for an explanation.
In order to use the flow velocity sensor, the cross sectional area of the flow
channel crossSection
must be specified in m_{2}
. For a
circular flow channel (e.g. a round pipe) of diameter diameter
, the
cross sectional area can be specified as crossSection = diameter *
diameter / 4 * Modelica.Constants.pi
. See
IBPSA.Fluid.Sensors.Examples.Velocity for an example implementation
with diameter = 0.1
.
