Galvanized Steel 9-Inch Parshall Flume

9-inch Parshall Flume

Description:

The 9-inch Parshall flume is useful in measuring a range of different flows.  Water right and surface waters are common applications for 9-inch Parshall flumes, but spring discharges and edge-of-field flow are also applications for the flume.

Galvanized Parshall flumes should never be used on sanitary flows.

Material of Construction:  

• Galvanized steel

Flow Rates:  

• 0.0906 - 8.866 cfs (cubic feet / second)
• 40.66 - 3,979 gpm (US gallons / minute)
