A totalizing inlet control is well-suited for an equipment module. The example below consists of three control elements: a coarse control valve, a fine control valve, and a flow meter. These control elements work together to provide inlet control to a tank.
Each control element is controlled by a control module as shown in the following table.
Control element |
Associated control module |
Control module function |
Coarse control valve |
COARSE_VALVE |
Performs simple state-driven control. The two states are Valve:Open and Valve:Closed. |
Fine control valve |
FINE_VALVE |
Performs simple state-driven control. The two states are Valve:Open and Valve:Closed. |
Flow meter |
FLOW_METER |
Provides a reading of total flow. |
The following sections describe the control modules, the equipment module, and how the control modules are added to the equipment module.
