Parshall Flume Manufacturer

Our experienced production and design leads have decades of experience when it comes to:

  • Applying
  • Designing
  • and Manufacturing Parshall Flumes 

We aren't a distributor, reseller, or catalog company.  

We are manufacturers...manufacturers who take pride in their work and who know Parshall flumes inside-and-out!

Openchannelflow offers the widest range of materials of any Parshall flume manufacturer!  

We aren't talking occasional one-off construction, but day-in-day-out, Openchannelflow offers Parshall flumes in the widest range of materials of anyone...period.

Openchannelflow can provide you with just about any Parshall flume size - from the small 1-inch to the giant 144-inch.  Openchannelflow produces all standard ASTM / ISO standard Parshall flumes widths up to 12-feet.

Now, as a short-throated flume, each Parshall flume size must be independently rated.  Because of this, Openchannelflow doesn't offer odd, non-standard Parshall flume sizes like the 30, 33, or 42-inch sizes that some "manufacturers" offer.  Their dimensions and, more importantly, discharge equations are not set and won't provide the same level of accuracy that ASTM / ISO standardized Parshall flumes will.

At Openchannelflow, we know that you aren't done just because you get a flume.  You need help in siting, installing, and maintaining your investment.
