Mounting & End Connections
Concrete Channels
Concrete encapsulation is the most common method of installing a Palmer Bowlus Flume as the flume was initially designed to be installed in-line with sewer piping in concrete manholes or vaults.
The flume is set in an oversized, roughed-in channel and then grouted into place. To help secure the flume during installation and make sure that it does not float out of place, wire is run through the anchor clips on the outside of the flume back to rebar before the grout pour begins.
In both concrete and earthen channel installations, the inside of the flume must be cribbed and weighted so that the flume does not shift out of place or the sidewalls / floor distort. Once the installation has been completed, the cribbing is removed.
Integrated Enclosures
Above grade industrial flows may require that a small monitoring flume be secured. For those applications, Openchannelflow offers factory integration of 4 to 10-inch Palmer Bowlus Flumes into one of our Redstone Fiberglass Equipment Enclosures.
The result is a secure, integrated solution that allows for the accurate measurement of flows while maintaining data integrity.
Flow Metering Manholes
For applications where below grade flow monitoring is required, Openchannelflow offers Palmer Bowlus Flumes integrated into our fiberglass Packaged Metering Manholes.
End Adapter
End connections for Palmer Bowlus Flumes revolve around the use of a bulkhead. For a Palmer Bowlus, a bulkhead is simply a flat, vertical plate attached to the inlet / outlet of flume.
Bulkheads can be provided with pipe stubs, flanges, or caulking collars to connect to new or existing piping.
Staged Manhole Transitions
Openchannelflow can mold curved ends on a Palmer Bowlus Flume. Curved ends allow the flume to be attached directly to a manhole. This eliminates the need to either form a transition or have a pipe connection to the flume.
Staged transitions are available for select sizes of Permanent Style Palmer Bowlus Flumes with approach sections and manhole diameters. Contact Openchannelflow for additional details.
Flume Stand
For applications where the flume is to site above grade, Openchannelflow can provide stands to raise the flume. The stand can be molded into the flume, or it can be a separate structure on which the flume is mounted.
