ABSTRACT:
The present invention provides an improved meter installation for a deep underground pipeline employing a meter pit. Pre-coiled, flexible tubing lengths are coupled between the ends of the pipeline in the pit and a flowmeter which is also housed within the pit. The meter is vertically movable within the pit. As the meter is raised, the pre-coiled tubing uncoils or expands, and as the meter is lowered, the pre-coiled tubing re-coils or contracts.
The meter installation of this invention is particularly useful for water metering in pipelines laid a substantial depth below ground level--as, for example, in cold plains states. The present system provides a meter reader, repairman, or the like, with ready access to the meter without the necessity of physically entering the pit. The meter is easily raised to ground level without interrupting the flow of liquid therethrough.
