BUILT TO N.I.S.T HANDBOOK 105-3STANDARDS AND API MANUAL OF PETROLEUM MEASUREMENT STANDARDS CHAPTER 4 2 . CALIBRATION FACTORY CERTIFIED USING STANDARDS TRACEABLE TO NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY. 3 . NOMINAL CAPACITY 5000 LITTER – CAUBRATED “TO DELIVERD” AT 15 DEG C 4 . NOMINAL DIAMETER 1.9M 5 . NOMINAL HEIGHT 3.4M 6 . PROVER WEIGHT (DRY) 1570 LB 7 . METERIAL TYPE 304 STAINLESS STEEL 8 . DRAIN VALVE CENTER DRAIN, 4 INCH BALL VALVE 9 . DESING REINFORCING BANDS TO PREVENT DISTORTION OF PROVER WHEN FULL WITH LIQUID AND WHEN BEING TRANSPORTED. 10 . TEMPERATURE MEASUREMENT (2) STAINLESS STEEL THERMOMETER WALLS, ONE IN THE MIDDLE OF THE BODY AND ONE NEAR BOTTOME OF BODY. 11 . LEVEL INDICATION (2) SPIRIT LEVELS LOCATED 90 DEG FROM ONE ANOTHER 12 . VOLUME INDICATION ALUMINUM GRADUATED SCALE 13 . SCALE GRADUATIONS 500 ML INCREMENTS 14 . REQUIRED SCALE RANGE ±22500 MLLITERS. THE GAUGE SCALE SHALL BE GRADUATED BOTH ABOVE AND BELOW THE NOMINAL CAPACITY GRADUATION BY AN AMOUNT NOT LESS THAN 1% OF THE PROVER VOLUME. 15 . TOLERANCE 0.05% SCALE ACCURACY 16. DATA PLATE ENGRAVED BRASS OR STAINLESS STEEL 17 . GAUGE GLASS FITTING STAINLESS STEEL 18 . LIFTING LOOPS (2) LIFTING LOOPS ATTACHED TO TOP BAND OF PROVER 19 . SIGHT FLOW INDICATOR INSTALLED BETWEEN PROVER DRAIN VALVE AND LEVELING BALL JOINT TO ENSURE DRAIN TIME MEETS NIST (30 SECOND AFTER MAIN FLOW CESSATION) DRAIN REQUIREMENTS. ALSO USED TO CHECK DRAIN VALVE FOR LEAKAGE. 20 . FILL STAINLESS STEEL “TOP LOADING-SUBMERGED FILL” PIPE PASSES THROUGH THE UPPER CONE AND EXTENDS TO THE BOTTOM CONE, REDUCING FOAMING WHILE FILLING. 21 . NECK COVER STAINLESS STEEL HINGED LOCKING COVER FOR TOP OF NECK TO PREVENT CONTAMINATION OR DAMAGE DURING TRANSPORTATION. ANOTHER COVER PROTECTS THE GAUGE GLASS FROM ACCIDENTAL BREAKAGE. 22 . LEGS (3) NON-ADJUSTABLE BOLT DOWN LEGS
