1-inch Parshall Flume

Description:

Developed in 1960 at the Colorado Agricultural Experiment Station, the 1-inch Parshall flume is commonly used to measure water flowing in creeks, furrows, irrigation canals, and channels.

Aluminum Parshall flumes are lightweight and abrasion resistant and are an excellent choice where site access is limited.
