*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.
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 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.
