erance not exceed ±0.3%，repeated measuring no more than 0.15% as fuel dispenser is operated within the flow range between maximum flow-rate (Qmax) and minimum flow-rate (Qmin fuel dispenser ). Flux scope is also called measurable range --- between minimum measured value and maximum flow-rate within basic tolerance. The ratio of maximum flow rate to minimum flow rate is called measurable ratio. In model testing the value is 10 to 1. Accuracy testing is conducted at six flow points within the measurable range so as to get their tolerances. This relation between tolerance and flux is called the tolerance nature of flow meter. The less flow tolerance the better. Measurable range ratio is 10 to 1 as fuel dispenser being left factory, testing three flux points, that is, Qmax, 0.4 Qmax, 0.1 Qmax . However, the ratio in operation place is 5 to 1, only testing two flow points -- Qmax , 0.2 Qmax . Minimum measured volume testing Testing purpose is to assess indicative tolerance when refueling by minimum measured value. Relevant regulations stipulate that the minimum flow rate don’t surplus 5L as for a fuel dispe fuel dispenser nser with maximum flow rate no more than 60L. Its maximum tolerance in terms of minimum measured value don’t exceed ±0.5%, measurable repeatability no more than ±0.25%. Flow stoppage testing The testing is conducted in order to define the possible tolerance range that generated in refueling progress in which hydraulic flow stop suddenly due to some accidents like power cut. Vapor separator performance testing It is conducted to value the capacity of vapor separator how much vapor would be divided from oil. Vapor separator’s function is to ensure that media passing over flow meter should be in single direction without any foam or bubble. Otherwise, flow meter can’t get right value of measurement. Volume fluctuation testing The test is aimed at defining the hose’s inner cubage variability of fuel dispenser under maximum pressure condition. According to fuel dispenser’s working prin fuel dispenser cipal, hose always
