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.

Galvanized steel flumes shouldn't be used to measure sanitary flows.

Material of Construction:  

• Galvanized steel

Flow Rates:  

• 0.0065 - 0.4783 cfs (cubic feet / second)
• 2.920 - 214.7 gpm (US gallons / minute)
• 0.0042 - 0.3092 mgd (US million gallons / day)

Flow Accuracy:
