Operation
As the liquid level in the UST approaches 95% capacity, the liquid
level raises the float. As the float rises it actuates the external/internal
magnetic couplers which release the flapper to be closed by the flow
of product. As the float continues to rise, the internal mechanism
pushes the flapper further into the product flow to allow actuation at
high or low flow rates. This sudden reduction in flow caused by the
primary flapper closing creates “line shock” to the fill hose which
signals the delivery driver that the tank is nearing 95% capacity.
As the float continues to rise to the 95% fill level, the secondary
closes, completely stopping the flow of fuel.
