2-inch Parshall Flume

Description:

One of the small Parshall flume sizes developed in 1960 at the Colorado Agricultural Experiment Station, the 2-inch Parshall flume is commonly used to measure water flowing in creeks, furrows, irrigation canals, and channels.

2-inch Parshall flumes are too small to use on sanitary flows as they will clog.
