The Palmer Bowlus metering flume is used for measuring water and wastewater in open channels or pipelines that are not under any pressure. This flume is normally installed in a "U" shaped channel fed by a pipeline such as storm drains and sewers. This convenient flume requires little redesign or special modification of circular conduits for installation. We offer a full line of standard flumes, along with countless custom structures used for open channel flow measurement. Sizes are available to measure everything from an intermittent trickle to a consistent canal. Manholes are manufactured as a total flow monitoring solution. The metering manholes may be supplied with any type of flume or flow measurement weir integral to the structure. Manholes are offered in two sizes, 48 inch or 60 inch diameters. Each size can be configured with a either a hinged fiberglass cover or a H-2O adapter cover for installation in a traffic areas. Both styles of covers are completely leak free and meet equivalent load ratings as those of the manhole body.
