Flume Product Description
|
Global Water offers water flumes constructed of high quality polyester resin and fiberglass. These flumes are durable, highly
accurate, and easy to install.
Global water offers primary device flumes that constrict an open channel's flow either horizontally or vertically or both. Once
the flume flow is backed up behind the constriction, there is a defined relationship between the upstream water level and the
open-channel flow through the constriction. This relationship can be determined either by an equation or a look-up table.
Global Water offers three standard molded flumes: the Palmer-Bowlus Flumes, the Parshall Flumes, and the H Flumes.
- The Palmer-Bowlus constricts the flow vertically and horizontally and can be molded to be inserted into an existing half-round
pipe. Click HERE for Diagrams and Palmer Bowlus flume table of Dimensions.
- The Parshall flumes constrict primarily horizontally, and are design for rectangular or trapezoidal channels. Click
HERE for Diagrams and Parshall flume table of Dimensions/Flow Data.
- H flumes attach to the ends of pipes where the water is free-falling. Click HERE
