*California 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.
**Evaluations determined these sensors' responses to the liquids shown above. Biodiesel blends B6-B20 meeting ASTM D7467 and biodiesel B100 meeting ASTM D6751 would also produce an alarm if the sensor threshold is exceeded. Responses to these fuels were not determined, but would be expected to be very similar to the diesel responses.
Evaluations determined that the Magnetostrictive Sump Sensor Series 857080-xxx responds to 100% Lubrizol Ultrazol 9888, 100% Afton OTR 8332G, and 100% Afton OTR 8843G. Alarm and response can be expected to be very similar to the response values listed above.
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.
Comparison of TLS-450 with TLS-350 series console showed comparable results when evaluated with representative sensors.
