Leak detection of petrochemicals, vegetable oils and others

NAR300

Compare

Field of application

Installed in a drainage sump pit near a tank or pump yard, the NAR300 system provides excellent leak detection of petrochemicals, vegetable oils, etc. Vibronics and conductive technologies are combined with a 2-level logic for simple, safe and highly reliable output for leak monitoring.

Ambient temperature: -20 to +60°C (-4 to +140°F)

Benefits

Two independent sensors are combined for accurate liquid leak detection
A conductive probe detects water or non-water liquid
A vibronic tuning fork confirms oil or air
No moving parts, long-life, reduces maintenance costs
Alarms outputs if cable fails, or water freezes, assuring fail-safe operation
Works with non-water soluble liquids independent of dielectric constant
