Parts in these systems may interact by many different means, such as software operations, discrete state transitions, flows of inputs and outputs, or continuous interactions. Source OMG Systems Modeling Language (SysML) 1.6
To signify that only water flows between the pump and the tank, we can specify an ItemFlow of type Water on the connector. Source OMG Systems Modeling Language (SysML) 1.6
For example, a pump connected to a tank: the pump has an "out" flow property of type Liquid and the tank has an "in" FlowProperty of type Liquid. Source OMG Systems Modeling Language (SysML) 1.6
A FlowProperty signifies a single flow element to/from a block. A flow property has the same notation as a Property only with a direction prefix (in | out | inout). Flow properties are listed in a compartment labeled flow properties. Source OMG Systems Modeling Language (SysML) 1.6
Conjugation is specified by a constraint giving the features of ~InterfaceBlocks according to those of their original InterfaceBlocks ... It is expected that tools conforming to this specification automatically create features of ~InterfaceBlocks. Source OMG Systems Modeling Language (SysML) 1.6
InterfaceBlock ... for example, in flow properties are conjugated as out flow properties and provided features are conjugated as required features. Source OMG Systems Modeling Language (SysML) 1.6
Ports appearing in block compartments can have their direction appear textually before the port name as “in,” “out,” or “inout” determined in the same way as the arrow direction. Source OMG Systems Modeling Language (SysML) 1.6
Ports with types that have flow properties in different directions or flow properties that are all in both directions, including have two open arrow heads inside them facing away from each other (<>). This includes the directions of nested and... Source OMG Systems Modeling Language (SysML) 1.6
This includes the direction of flow properties on nested ports, and if the port is full and its type is unencapsulated, ports on parts of the port, recursively. The arrows are perpendicular to the boundary lines they overlap. Source OMG Systems Modeling Language (SysML) 1.6
Ports with types that have flow properties all in the same direction, either all in or all out, can have an arrow inside them indicating the direction of the properties with respect to the owning block. Source OMG Systems Modeling Language (SysML) 1.6

A FlowProperty signifies a single flow element to/from a block. A flow property has the same notation as a Property only with a direction prefix (in | out | inout). Flow properties are listed in a compartment labeled flow properties. Source OMG Systems Modeling Language (SysML) 1.6
FlowProperty naming. Use anonymous or just 'i' for in, 'o' for out, and 'io' (or 'oi') for inout. "Trust the Type". For conjugation ~InterfaceBlock use 'o' for in, 'i' for out, and 'io' (or 'oi') for inout.
FlowProperty::direction : FlowDirectionKind [1] Specifies if the property value is received from an external block (direction="in"), transmitted to an external Block (direction="out") or both (direction="inout"). Source OMG Systems Modeling Language (SysML) 1.6
For Blocks and Interface blocks with one or more FlowProperty items, choose a direction convention and use it across one project.
