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.
