Specificity Results:
Manufacturer and evaluator claim sensors will
respond to any liquid but evaluator only tested for liquids identified above.
Manufacturer’s Specifications:
Manufacturer states that systems require no
calibration.
Annual functional test required.
Model DCS140D generates alarms on fuel detection and high liquid while Models
DCS140L and DCS140NL generate an alarm on liquid detection.
Comments:
Each sensor is reusable.
If liquid is detected at any of the threshold levels, a fuel
alarm will be triggered.
The output from the system can be used to shut down the turbines
when fuel is present or when water reaches the high level switch.
