As the float t <br /> rises it actuates the external/internal magnetic I <br /> couplers which release the flapper to be closed by 95%of rank <br /> the flow of product. As the float continues to rise,the Volume <br /> internal mechanism pushes the flapper further into <br /> the product flow to allow actuation at high or low flow <br /> rates. This sudden reduction in flow caused by the <br /> primary flapper closing creates "line shock" to the fill <br /> hose which signals the delivery driver that the tank is Tank B <br /> ottom ----------------------- ------- <br /> nearing 95% capacity. As the float continues to rise 0 + 16" (152 mm) Maximum <br /> to the 95%fill level, the secondary closes, completely <br /> stopping the flow of fuel. <br />
