FUNCTION SYMBOLS ARE BASED ON ANSI/ISA-S5.1. FUNCTION LABELS AND IDENTIFICATION ARE BASED ON DOCUMENT: N° RLNG-000-IC-PP-0001(INSTRUMENT & CONTROL NUMBERING PROCEDURE). TYPE OF VALVE BODY FOLLOWING SELECTION CRITERIA. REMOTE SENSING LINE (IF REQUIRED). ALL INSTRUMENT TAGS ARE PRECEDED BY THE UNIT NUMBER (SHOWN ON PID BY GENERAL NOTE). UNIT NUMBER WILL BE SHOWN ON INSTRUMENT TAGS, ONLY IN CASE OF UNIT NUMBER IS DIFFERENT OF PID UNIT NUMBER. A STRAIGHT RUN OF 10 HOLE DIAMETERS IS REQUIRED AFTER ANY R.O. PLATE OR AFTER THE LAST R.O. IN MULTIPLATE INSTALLATION. WHERE THE HOLD SIZE IS 10% N.P.S. AN ELBOW MAY BE INSTALLED IMMEDIATELY DOWNSTREAM. FOR ON-LINE ANALYSER AND TRANSMITTER, THE TYPE OF ANALYSIS IS DEFINED OUTSIDE THE SYMBOL: GC: GAS CHROMATOGRAPH O2: OXYGEN ANALYSER FID: FLAME IONISATION DETECTION ANALYSER H2O: MOISTURE ANALYSER FREE CL2: FREE CHLORINE ANALYSER

ALL TEMPERATURE ELEMENT WILL BE RTD TYPE UNLESS IDENTIFIED AS TERMOCOUPLE (TC) TYPE ON P&ID. FIELD INSTRUMENT LOCATION SHALL BE MENTIONED IN P&ID WITH BUILDING TAG.
