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.

Aluminum is an excellent material where weight and abrasion resistance are important.

Material of Construction:  

• Aluminum

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:

• +/- 2-5% (ASTM D1941)

Flow Formula (H = feet):

• Q (cfs) = 0.676 * H^1.55 
• Q (gpm) = 303.4 * H^1.55
• Q (mgd) = 0.4359 * H^1.55
