Controllers
“Controllers” in FluidFlow is a collective term for nodes that are used to model different devices for controlling flow, pressure, or temperature at a given point in a fluid transport system.
A controller node can be any of the following:
- Self Acting Pressure Sustainer
- Self Acting Pressure Reducer
- Self Acting Differential Pressure Controller
- Pressure Control Valve
- Flow Control Valve
- Gas Regulator
Except for gas regulators, controller nodes can be autosized to determine preliminary valve Cv values. They can also simulate system performance using control valve manufacturer data.
