requires annual certification of all leak detection equipment.
The certification of discriminating sensors should include
functional testing of both water and product detection capabilities.

xxx* - designates sensors in the 857060 and 857080 series containing:
857060 and 857080-101, -102, -111, -112, -121, -122, -211,
-212, -221, and -222
Comments:
One sensor length (24") was evaluated.
Results are typical for the other sensors in the 857060-xxx
and 857080-xxx series, regardless of length and programmability
options.
All sensors are based on the use of a magnetostrictive sensor
that is equipped with two floats. The lower float will only
float on water. The upper float will float on fuel as well
as water.
Results for the "water alarm" threshold will vary
based upon programmed alarm levels.
The "fuel alarm" is based upon a fixed threshold
and is not programmable.
Systems containing these sensors can be programmed to alarm
continuously and to shut down the dispensing system.
Sensor will issue an alarm if it is raised from the bottom
of the containment vessel.
Sensors are reusable.
Vendor claims sensors are easily removable, cleaned, and reinstalled
if an alarm is triggered or for periodic testing.
