What do FRC/TRC mean?
Thread Content
There are many symbols in the process flow diagram, such as FRC and TRC. I guess they are symbols for control units, but I’m not sure what they each mean. Thank you for your help.
This is a code specific to instruments, and it is indicated on the design drawings. Typically, F stands for flow rate, R stands for recording, and C stands for control, indicating that this is a flow control module capable of recording trends. Of course, T stands for temperature, P stands for pressure, and there are many others; there are dedicated books on the forum.
SHB-Z02-95: Instrument symbols and markings – this standard provides a very detailed explanation! http://bbs.hcbbs.com/viewthread.php?tid=42163&highlight=%D2%C7%B1%ED%B7%FB%BA%C5
On flowcharts, F is used to indicate the specific role and function of a instrument: T for temperature, P for pressure; L for liquid level, R for recording, and C for control
FRC – Flow rate recording control; TRC – Temperature recording control
F: Flow rate, R: Recording, C: Control, T: Temperature, P: Pressure
F: flow rate; T: temperature; P: pressure; R: record; C: control
F: Flow rate, R: Recording, C: Control, T: Temperature, P: Pressure, L: Liquid level, A: Analysis
