Abstract
The monitor allows for the non-destructive determination of the status of a liner disposed within a conduit. The conduit may, for example, be an elbow, valve, pipe. At least one wire is disposed within the liner in an area of concern. The wire is connected to a receptacle located on the conduit. A status display plugs into the receptacle and checks the continuity of the wire. If a wire is broken, this information is displayed, indicating a potential problem with the liner.
Claims8
A conduit having an internal status indicator, the conduit comprising a wall, an interior liner adjacent to the wall, a cavity extending into the conduit, at least one deteriorative wire substantially embedded in the liner, the cavity adapted to accommodate a receptacle connected to the wire, and the receptacle adapted for association with an information display.
A system for determining the status of a conduit liner, the system comprising:
- a) a conduit;
- b) a liner disposed within the conduit;
- c) at least one continuous deteriorative wire embedded within the liner;
- d) at least one wire communicating with an externally connectable receptacle associated with a cavity extending into the conduit;
- e) the receptacle adapted to communicate with a liner status display device;
- and
- f) the wires communicating with external resistors configured in parallel circuitry, the resistors communicating with the liner status display device, and the liner status display device measuring and reporting the resistance of the parallel circuitry.
A system for determining the status of a conduit liner, the system comprising:
- a) a conduit;
- b) a liner disposed within the conduit;
- c) at least one continuous deteriorative wire embedded within the liner;
- d) at least one wire communicating with an externally connectable receptacle associated with a cavity extending into the conduit;
- e) the receptacle adapted to communicate with a liner status display device;
- f) the liner status display device adapted to sense and report the condition of the wire;
- and
- g) the liner status display device including at least one light source, the light source adapted to indicate the condition of at least one wire.
