We manufacture and supply a wide range of flumes from fiberglass, polypropylene and stainless steel: from compact Cartridge flume, through Badger Meter Manhole flume to Parschall flumes.

Manhole flume is a low head loss flow measurement primary device especially designed to fit into standard manholes. The upstream approach and throat velocities significantly reduce solids deposition.

Its fiberglass reinforced polyester construction, for long life and corrosion resistance, incorporates a low head trapezoidal design in conjuction with a hooded outlet collector and pipe spud. The hooded section, following the throat, prevents bypass leakage under normal flows, yet allows nearly unrestricted flows during emergency conditions.

The Parschall flume is open channel primary element. A distinguishing characteristics of the flume is the download sloping invert of the throat. This feature gives the Parschall flume ability to operate at higher ratios of downstream to topstream heads than any other such device. The flume operates with a small energy loss or change in channel grade, about one-fourth that of weirs having the same crest length. The Parschall flume is made from fiberglass reinforced polyester or stainless steel.
