Ramp Flumes Product Description
Global Water Ramp Flumes are low cost water measurement
equipment, a flume built for easy installation and
accuracy. The Ramp Flumes are built from high grade 16
gauge galvanized steel and will resist most corrosive
environments. The design utilizes rigid flanges and
bracing to allow the use of soil as a backfill during
installation. The Ramp Flumes are shipped unassembled
to minimize the cost of freight. All Ramp Flumes from
3.5 to 10 cubic feet per second, can be shipped by UPS.
No special tools are needed for assembly as only a nut
wrench and screw driver are necessary.
Installation
Installation of the Ramp Flumes is simple and straight
forward. The ramp flume must be level from end to end
and side to side. The Ramp Flumes can be transported to
the installation site by hand horse, truck or ATV. The
large ramp flumes are heavy and will require excavation
equipment for lifting and site preparation. The Ramp
Flumes does not require surveying or complicated
excavation for installation. The cost of installation
will be minimal. Gloves should be used for safety
during installation.
Accuracy
Extensive testing and evaluation under field and
laboratory conditions have shown the Ramp Flumes
consistently achieve accuracy to within 3%, when
properly installed. The increased flow velocity in the
throat section discourages sediment accumulation in this
part of the flume. The approach section near the gauge
has a self-cleaning function which provides long
intervals for debris free operation and consistent
accuracy. This produces long periods of time between
required cleaning and maintenance.
Advantages of ramp flumes:
- Direct reading flow gauge
- No need for flow rate tables
- Ease of flume installation
- Adaptable to various canal shapes and sizes and
reduces upstream ponding
- Can be used to line canals
Ramp Flumes Options
Choosing the correct flume size for your application is
important. We suggest using the smallest size flume
that will accommodate your channel's flow. The Ramp
Flumes are available in several standard sizes, as shown
below.
