  • Oil Leak Detector NAR300 System High Temperature - Technical Information

    This system is designed to be installed in a pit within an oil retaining
    dike, a plant, or a sump pit near a pump yard, where it can provide the
    ultimate in
    leak detection function for oil, petrochemicals or vegetable oils.
    The Oil Leak Detector NAR300 Systemfor high temperature utilizes
    detection function, conductive, to monitor the condition.
    This NAR300 system for high temperatureissuitable for a pit using
    steam draining conduit for anti-freezing and high temperatures (≤100°C).
    The accurate and minimal equipment configuration ensures safe operation
    of tank yard.

    ultimate in
    leak detection function for oil, petrochemicals or vegetable oils.
    The oil leak detector NAR300 systemutilizes two separate detection
    functions, a conduction sensor and a tuning fork sensor, to monitor
    conditions.
    Highly accuratealarm recognition is attained through a 2-stage logic
    process, which ensures safe tank yard operation, with minimal equipment
    configuration.
