Of all of Openchannelflow's products, our Weir Boxes receive the most calls for customization; more so than our flumes, manholes, or even equipment shelters.

Bubbler style flow meters provide the most accurate measurement of level in open channel applications; more accurate than ultrasonic or even pressure transducer flow meters. Using an internal air compressor to push a measured volume of air through a vinyl or Teflon bubbler line,…

The typical bracket used to mount an ultrasonic sensor over a flume or weir is a contractor fabricated one-off assembly. These assemblies often mount the ultrasonic sensor too high, too close to the flume / weir sidewall, or aren't sufficiently rigid - making accurate flow…

The Iowa Institute of Hydraulic Research has posted an excerpt of one of their older videos, Fluid Motion in a Gravitation Field: Flow Over Weirs. The video, developed with the support of the National Science Foundation, covers, among other things, the need for aeration of a weir…

In its simplest form a Packaged Metering Manhole (PMM) consists of a primary device (typically a flume or weir) molded into a fiberglass (FRP) manhole. By directly factory integrating the primary device, a single-piece, drop in-place flow monitoring solution is created.
