To illustrate this linear P-control relationship, consider the P-only control that controls the level of a fluid in a tank. Initially, the flow into the tank is equal to the flow out of the tank. However, if the flow out of the tank decreases, the level in the tank will increase because more fluid is entering than is leaving.

I have an open ended question about P&IDs and Process Control Narratives (PCNs). Our organization has been using P&IDs for a long time. (We also used to use loop diagrams until it didn't make as much sense to use loop diagrams since with the advent of DCS systems and PLCs, the field instrumentation and devices get connected to the DCS or PLC …
The process of creating a P&ID diagram involves a sequence of steps that begins with simpler diagrams and progresses to a more detailed P&ID. The typical steps are: BFD (Block Flow Diagram: start with a BFD to outline the main process operations and flows – i.e. to conceptualize the system at a high level of abstraction), PFD (Process Flow Diagram: next, …
A Piping and Instrumentation Diagram (P&ID) is a schematic layout of a plant that shows the units that will be used, the pipes that will connect them, and the sensors and control valves. Storage tanks, surge tanks, pumps, heat exchangers, reactors, and distillation columns are common structures seen on a P&ID. The last three are the most common single-unit …
TY 101 is an I/P (I to P) converter i.e current to pneumatic signal converter. This is because TY 101 receives an electrical signal from TIC 101 and then converts it to a pneumatic signal which then acts on the control valve shown in the P&ID above. The control valve then opens or closes to increase or decrease water flow into the heater exchanger.
