EZ Ramp Flume

EZ Flow Ramp Flume

Open Channel Flow Monitoring Ramp Flumes

The EZ Flow Flume is a galvanized steel ramp flume designed to measure flow in open ditches.  The most common use for this flume is irrigation flow monitoring. The EZ Flow Ramp Flume can be used in dirt and concrete ditches.  There are currently 4 sizes available.  These flumes are generally more economical than a fiberglass flume or a custom welded steel flume.  We build these flumes in quantities to lower the cost, the three smaller sized flumes are shipped un-assembled in a single box.  The largest size (20 CFS) will ship un-assembled in 3 boxes. By shipping the flumes un-assembled they can ship by UPS or FedEx.

Intermountain Environmental, Inc. (IEI) is now the manufacturer of these flumes.  Made in the USA. NuWay or Nu-Way Flume & Equipment Company is no longer an active business.
