Abstract
A meter reading apparatus includes a telescopic tubular viewer attached to the underground meter and provides a clear sight path through water in the meter box for easy meter reading. In a first embodiment, the viewer member is connected to the meter by a collar, brackets and clamps including a clevis and J-shaped connecting rod. In a second embodiment, the viewer is connected to the meter by a collar integrally formed with the meter and including threads for engaging the viewer. In both embodiments, the viewer is moisture tight and includes a transparent sealing lens at the top end, and an O-ring seal at the bottom end between the viewer and the meter. A coiled air tube may be provided to maintain ambient pressure inside the viewer during extension and retraction.
