CONSTRUCTION BUILT TO N.I.S.T. HANDBOOK 105-3 STANDARDS AND API MANUAL OF PETROLEUM MEASUREMENT STANDARDS CHAPTER 4 CALIBRATION FACTORY CALIBRATED USING STANDARDS TRACEABLE TO NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY CERTIFICATION FOR LEGAL METROLOGY NOT INCLUDED NOMINAL CAPACITY 200 GALLON - CALIBRATED "TO DELIVER" AT 60 DEG F NOMINAL DIAMETER 48 INCHES NOMINAL HEIGHT 65 INCHES PROVER WEIGHT (DRY) 380 LBS. MATERIAL TYPE 304 STAINLESS STEEL DRAIN VALVE CENTER DRAIN, 2 INCH BUTTERFLY VALVE DESIGN REINFORCING BANDS TO PREVENT DISTORTION OF PROVER WHEN FULL WITH LIQUID AND WHEN BEING TRANSPORTED. TEMPERATURE MEASUREMENT (1) STAINLESS STEEL THERMOMETER WELL LOCATED SO THAT THE CLOSED END IS AT THE APPROXIMATE CENTER OF THE PROVER. LEVEL INDICATION (2) SPIRIT LEVELS LOCATED 90 DEG FROM ONE ANOTHER VOLUME INDICATION ALUMINUM GRADUATED SCALE SCALE RESOLUTION 10 CUBIC INCH MINOR GRADUATIONS REQUIRED SCALE RANGE ± 350 CUBIC INCHES. THE GAUGE SCALE SHALL BE GRADUATED BOTH ABOVE AND BELOW THE NOMINAL CAPACITY GRADUATION BY AN AMOUNT NOT LESS THAN 1.5 % OF THE PROVER VOLUME TOLERANCE 0.02% SCALE ACCURACY DATA PLATE ENGRAVED BRASS GAUGE GLASS FITTING STAINLESS STEEL LIFTING LOOPS (2) LIFTING LOOP ATTACHED TO TOP BAND OF PROVER SIGHT FLOW INDICATOR INSTALLED BETWEEN PROVER DRAIN VALVE AND LEVELING BALL JOINT TO ENSURE DRAIN TIME MEETS NIST (30 SECONDS AFTER MAIN FLOW CESSATION) DRAIN REQUIREMENTS. ALSO USED TO CHECK DRAIN VALVE FOR LEAKAGE. FILL STAINLESS STEEL "TOP LOADING-SUBMERGED FILL" PIPE PASSES THROUGH THE UPPER CONE AND EXTENDS TO THE BOTTOM CONE, REDUCING FOAMING WHILE FILLING. 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 AND CAN BE SECURED LEGS WITH A LOCK FOR SAFETY. (3) BOLT DOWN LEGSR. ADJUSTMENTS ARE MADE BY CRANK HANDLES ON TRAILER AVIATION FILL SINGLE POINT CONNECTION ADDED TO BODY OF PROVER
