3-inch Parshall Flume

Description:

The largest of the small Parshall flumes developed at the Colorado Agricultural Experiment Station, the 3-inch Parshall flume is commonly used to measure water flowing in creeks, furrows, irrigation canals, and channels.

The 3-inch Parshall flume is the smallest Parshall flume that should be used on sanitary flows.

Galvanized Parshall flumes should never be used on sanitary flows.
