Abstract: A method for installing a sensor assembly in a fire hydrant includes sequentially feeding components of the sensor assembly through an aperture in an upper standpipe of the fire hydrant. The components of the sensor assembly include a sensor unit, a conduit coupled with the sensor unit and extending away therefrom, and a series of rigid tubes surrounding the conduit and arranged in an end-to-end manner. The conduit is fed through the aperture along with the series of rigid tubes, and at least one of the series of rigid tubes has a length greater than a diameter of an interior of the fire hydrant.

Abstract: A sensor assembly includes a sensor unit including a generally rigid sensor housing and at least one electronic sensor component, a conduit coupled with the sensor unit and extending away from the sensor housing, and a rigid support structure supporting a portion of at least one of the conduit or the sensor housing at a first end adjacent the sensor unit and extending away from the sensor unit to a length of at least about 6 feet. The rigid support structure configured to maintain the sensor unit within an internal structure for monitoring using the electronic sensor component.
