This paper describes a fully automatic oil-pipe-line pumping station built by the A.S.M.E. Special Research Committee on Automatic Pipe-Line Pumping Stations. The station is in operation at the grounds of the International Petroleum Exposition at Tulsa, Okla., and is being used as an experimental laboratory to complete the development of automatic pumping and to fully test out and coordinate the equipment units used in its construction. When this development is completed, the committee will make a final report indicating all changes, and will give a description of the piping and electrical circuits finally resulting from this research.
