Legend ROCHELSOPN=(Refill Operator Controlled Hose End Level Sensing Overfill Prevention Nozzle) Notes: 1 it is assumed that minimum visible leaks would be detectable at one cup per month. Leaks larger than that rate would be detected sooner. Z it is assumed that the minimum interval between visible checks would be 4 days(long weekend). gpm=gallons per minute
