Flow Bell

InfraSteel’s FLOW BELL is a flared beveled inlet attachment, designed to improve the flow characteristics of the rehabilitated structure. Each FLOW BELL is manufactured for the inlet of the specific site, and it may be welded to the liner or both the liner and headwall. A typical design is ½” per diameter foot in width, with a beveled edge. Other widths and angles can be manufactured, including side and slope-tapered entrances. These features decrease the head loss as the flow enters the culvert. Flow Bells are expected to be used widely on future designs; due to increasingly common, rising headwater, limitations.
