    A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes.

    It is numbered with a stylized flag symbol surrounding the number (or sometimes a delta symbol). A general note applies generally and is not called out with flags. 2. Find number: "FN" meaning "find number" refers to the ordinal number that gives an ID tag to one of the constituents in a parts list (list of materials, bill of materials).

  4. Rotameter - Wikipedia

    en.wikipedia.org/wiki/Rotameter

    A rotameter is a device that measures the volumetric flow rate of fluid in a closed tube. [ 1 ] It belongs to a class of meters called variable-area flowmeters , which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect.

    The flowrate of purge gas is set by rotameter (FIC) or fixed orifice plate (FO). A low flow alarm (FAL) warns operating personnel that the purge flow has reduced significantly. [8] Pipelines are monitored by measuring the flowrate of fluid at each end, a discrepancy (FDA) may indicate a leak in the pipeline.

  9. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    A rotameter is an example of a variable area meter, where a weighted "float" rises in a tapered tube as the flow rate increases; the float stops rising when area between float and tube is large enough that the weight of the float is balanced by the drag of fluid flow. A kind of rotameter used for medical gases is the Thorpe tube flowmeter ...
