Lower detection limit (ml)


(6.7 ounces)


(6.12 ounces)


(18.3 ounces)

*The fall time was not determined.  Evaluator notes that fall time is irrelevant because the only way to reset the system is to remove the liquid from the float sump and manually reset the shear valve.

Specificity Results:
Responds to any liquid in sufficient quantities to raise the float which trips the shear valve.  No additional materials tested.

Manufacturer’s Specifications:
The Model B-2000 and Model B-8600 systems use a float coupled to the shear valve mechanism of the dispenser.  When any liquid (water or fuel) enters the sump in sufficient amounts to raise the float, the shear valve is tripped, preventing dispensing of fuel from that particular dispenser.  The systems are designed with baffles that initially restrict the tripping to the dispenser in question.  If sufficient liquid enters the section, it will overflow the baffle and trip the shear valves on the adjacent product inlet within the dispenser pan.
