system controlled by one or more
controllers. The entire system of controllers is connected by networks for
communication and monitoring.
DCS is a very broad term used in a variety of
industries, to monitor and control distributed equipment

[ pdf ] Automation Control Systems PLC Basics
Topic: PLC (Programmable Logic Controller)
Automation control systems.
These control systems are used in manufacturing plants of all types, and
some other applications that you may not have considered.
The control systems are built around special devices, designed to
operate industrial machines, and processes. We call these devices
Programmable Logic Controllers (PLC) and Programmable Automation
Controllers (PAC).

[ pdf ] DEVELOPMENT OF ORIFICE METER STANDARDS
Topic: Flow MeasurementThis paper is for the purpose of reviewing how we have arrived
at the orifice meter standards, what is their value and what we
can expect in the future. It is of value to review this background
since respect for the orifice standards (and other standards) has
diminished. This can lead to real chaos for the gas industry. The
last way you want to solve your measurement problems is based
on personal opinions – this is the purpose of the standards,
because it represents consensus data with legal standing
