A flow network is a system composed of pipes that connect multiple inventories such as plastic chests, pumps, flow regulators, distillation columns, steam crackers, merox treatment units, chemical processors and others. A flow network is defined by a pump. Each pumped connection is its own flow network. Right-Clicking (activating) the pump allows the insertion of fuel and indicates the status of the flow network. Red text means that the flow network is not valid. Green text means that it is valid.
A flow network is valid when it connects a source to an default target output. If flow regulators are added into a flow network, the items that are placed in the various slots are selectively piped in that direction. Thus a single flow network could have many, many branches as dictated by the flow regulators.
Whenever a flow network runs into a target inventory, a new flow network can be created that pumps items out of that same inventory. For instance, you could distill things multiple times in an automated fashion using several flow networks. Each flow network must have a default target.
All Flow-enabled inventories follow a universal symbol convention to demarcate inlets and outlets.
- Blue squares indicate inputs and are mapped to specific input slots on the inventory GUI.
- Red squares indicate inputs for the fuel slot on fueled inventories (pumps, lamps, and other small inventories do not have this available)
- Green squares indicate outputs for the resultant products to be piped out of the inventory
Networks should be built in the following order:
- Placement of Inventories in the world at their desired locations, preferably with easy access to their demarcated connector points
- Placement of Pumps that push or pull items into and out of inventories. There must be one pump per pipe section that transfers items between inventories.
- Placement of pipes from the destination to the origination to ensure items move in the right direction. Pipes are directional and will prevent flow networks from working if placed inversely.
As shown in the red circle in the image below, one pump pulls the outputs of the distillation column to a chest and another pushes the items from the plastic chest to a flow regulator. Only one pump is necessary to push items through multiple outlets in a Flow Regulator
