result during approval progress. The other is to make adjustment as temperature fluctuate 20 degree. Stopwatch, minimum value 0.1 second, is used for measuring how long a certain volume medium discharge out of fuel dispenser so as to calculate its flow rate. Gradienter, prec fuel dispenser ision being 0.05mm/m, measures the degree of level. Article III Indicating appraisal method and data processing Appraisal of fuel dispenser actually is an indicating access. Presently, cubage compare method is mostly used defining basic tolerance between the volumes flow over flow meter and in metal standard measurer. Di fuel dispenser agram 6-2 is illustrated the fuel dispenser’s appraisal flow. 1: Check valve 2: Pump 3: Vapor separator 4: Flow meter 5: Indicating device 6: Hose 7: Nozzle 8: Standard measurer 9: Measurer 10: Switch & zeroing 11: Container 12: Motor 13: Tank 14: Filter net Diagram 6-2: Appraisal of fuel dispenser using metal standard measurer Preparation before appraisal Place metal standard measurer on the hard ground and adjust with gradienter. It also put on vehicle or other bracket, as long as not waving or vibration during appraisal progress. Metal standard measurer should be earthing- connected. It is suggested to connect the measurer to ground terminal of fuel dispenser, making them being same potential. Running-in and wet measurer. Putting indicator device at zero, open nozzle and observe oil indicator. Oil is transparent as there is no foam in it. If have foam or bubble oil would be feculent and opaque. If foam exists in oil for a long time, fuel dispenser would have trouble. Appraise again after solving failure. Close nozzle as measurer full of oil. Empty measurer in accordanc fuel dispenser e with relative method and time, and shut off bottom valve, putting measurer in preparation state. Appraisal procedure of indicating valve Set unit price; Adjust flow to the maximum Qmax; Wet measurer and place it according to regulation; Tune indicator finger to zero position; Infuse measurer as preset volume, measure outlet t
