through the process pipe and transmitting the relevant signal to the PID 
controller. The process flow is regulated and kept as near as possible to the 
set point by the control valve through the received signal as an output of the 
controller action. Hence, the correct selection of each loop element and the 
proper tuning of PID controller is the key to oscillation free control operation. 
In order to realize and implement the flow control loop, Emerson test rig 
has been utilized as a model of flow control application. Following equipment 
has been reviewed and selected for the implementation of the flow control 
loop: 

Coriolis Flow Meter Elite series+2400 Tx 

EZ control valve - 667 actuator- DVC6000 

DeltaV Hardware & Software (Control Studio) 

Variable Frequency Drive 
The implementation process has been started by configuration of the 
control system utilizing DeltaV software. During the configuration, the 
function blocks have been built and downloaded to the controller by 
establishing the proper communication between the devices. Following the 
system start up, necessary tuning of the controller has been performed in 
order to ensure proper and smooth operation of the flow control system at 
the test rig. As a result of successful control operation, the following output 
documents have been developed: I/O list, BOM, C&E diagram, Electrical 
Diagram, Interconnection diagram, Instrument index, P&ID. 
To summarize, in the pre-implementation stage, the technologies 
required for building a flow control loop was selected alongside with the 
identification of the key parameters belonging to the selected devices. After 
completing the software and hardware configuration, the proper flow control 
loop has been ensured through DeltaV control system during implementation 
providing the relevant output documents. Moreover, the further development 
is achieved by creating instructions for the university undergraduates to 
perform the implementation as a laboratory work.
