    DLP-1 & DLP-2
    Designed to detect the presence of liquid in sumps, attached access pipes, annular spaces, or locations requiring a small float-operated sensor. Two models to fit 1-1/2″ and 2″ standard piping.


    Designed for use in the annular space of double-wall fiberglass tanks to detect the presence of conductive liquid. When combined with Warrick® DMS or TA alarm panel, DWP-25 sensors can detect the presence of water or other conductive liquids in normally dry annular spaces.


    Designed for use in the annular space of double-wall fiberglass tanks to detect hydrocarbon liquids. When hydrocarbons are present, a hydrocarbon wax pellet dissolves and closes a springloaded switch to signal a leak. This sensor is not reusable after exposure to hydrocarbons.


    Designed to monitor hydrocarbon vapors in wells or sumps by absorbing the vapors and triggering a switch. Should not be used where vapors are continuously present. Fits in standard 2″ pipe with cover.

    Utilizes conductivity probes and a reed switch-based float switch to detect the presence of liquid and differentiate between hydrocarbons and water. When combined with Warrick® DMS or TA two-channel alarm panel, the DSP-2 can discriminate between water and hydrocarbon liquids causing fault conditions.
