18-inch Parshall Flume

Description:

The 18-inch Parshall flume is useful for measuring both water rights / irrigation flows as well as surface water and edge of field flows.

Aluminum Parshall flumes are lightweight and abrasion resistant and are an excellent choice where site access is limited and portability is a concern.  Their light weight means that aluminum Parshall flumes generally require less manpower and equipment to install versus other flume materials.
