Understand Flow Path state

Based on the state of the valves inside of a Flow Network model, each segment can determine which injection or delivery devices are reachable. Combining a segment’s list of reachable injection/delivery devices with the flow direction of each of those injection/delivery devices allows each segment to be assigned a Flow Path state. Applications can then inspect a segment’s Flow Path state to quickly make decisions regarding it. The Flow Path state is stored in the RealTime database (RTDB) on the fnet table in the column segments[<SegmentNumber>].state.flowpath or in the State.FlowPathState property for any topographical segment in the Flow Network API.

Flow Path states will be discussed in the following sections:

• Flow Path state Open

• Flow Path state Closed

• Flow Path state Downstream Blocked

• Flow Path state Upstream Blocked

• Flow Path state Shut In

• Flow Path state Blocked
