Canal Automation Using the Electronic Filter Level Offset (EL-FLO) Method

by Lowell F. Ploss, Central Valley Project, Willows, CA, USA,



Document Type: Proceeding Paper

Part of: Hydropower: Recent Developments

Abstract:

Beginning in 1969, the Bureau of Reclamation began testing and refining an electronic filter level offset (EL-FLO) control system for canal automation. The control system uses a proportional method in which the upstream regulating gate opening is made proportional to the variation of the downstream water level to a desired target level. An EL-FLO plus RESET control system has been placed in operation on the Corning Canal of the Bureau's Central Valley Project. The paper summarizes the theory and development of the EL-FLO control system. It also describes the actual operating experience with the control system on the Corning Canal.
