WITSML - Product Flow Unit Component Schema. The name of the Product Flow Unit within the context of the Product Flow Network. The name of the facility for which this Product Flow Unit describes fluid flow connecton behavior. The name can be qualified by a naming system. This also defines the kind of facility. For facilities whose name is unique within the context of another facility, the name of the parent facility this named facility. The name can be qualified by a naming system. This also defines the kind of facility. For facilities whose name is unique within the context of another facility, the name of the parent facility of facilityParent1. The name can be qualified by a naming system. This also defines the kind of facility. The name and type of a facility whose context is relevant to the represented facility. An inlet or outlet port associated with this unit. If there is an internal network then the name of this port must match the name of an external port for that network. Any properties (e.g., volume, pressure, temperature) that are assigned to this port are inherently assigned to the corresponding external port on the internal network. That is, the ports are logically the same port. Similar to a node, there is no pressure drop across a port. Also similar to a node, conservation of mass exists across the port and the flow direction across the port can change over time if the relative pressures across connected units change. "A descriptive remark associated with this unit. Unique identifier for the Unit.
