Who Are the Leading Manufacturers of Flumes, Manholes, and Weirs

fiberglass flume Every year at Openchannelflow we talk with several hundred consultants, researchers, contractors and end-users about their flow monitoring needs.

Because we work extremely hard at answering all questions "flow” on this web site – and this blog in particular - we are often asked who are some of the manufacturers we compete with.

We've never been shy about being honest with respect to our competition, so below is a list of some of the manufacturers that have a solid history of offering flow measurement, conditioning, or control products. The list below does not include resellers, job shoppers, etc. - only integrated manufacturers

Plasti-Fab:
- Having been around for years, Plasti-fab is located in the Portland, OR area (Tualatin to be exact) and offers a range of flow and non-flow related products: flumes, metering manholes, enclosures, shelters (buildings), pipe hangers, staff gauges, scum baffles, and gates.
Warminster Fiberglass:
- Located in the Philadelphia area, Warminster Fiberglass has also been around for many years, with their primary product lines being fiberglass flumes, clarifier weirs, launder covers, doors, manholes, gates, control / filter consoles, and buildings.
Virtual Polymer Compounds:
- Formerly Corrosion Controls, is a manufacturer of flumes, metering manholes, shelters, booths, aerial lift buckets / repairs and is located in upstate Medina, NY (between Buffalo and Rochester), and resellers of staff gauges and manhole covers..

So there you go: 3 manufacturers to consider if you're getting quotes for your flow measurement, conditioning, or control project.

Now naturally, we'd like you to add Openchannelflow to that list, but we also believe you should have choices!

The key to a great flow measurement, conditioning, or control installation is simple and twofold:

The Quality of the Product
- Quality raw materials
- Excellent finishing
- Dimensional accuracy

The Support Quality
- Multiple support channels
- Are they are anxious to keep you happy as they are to make the sale?
- Warranty length

Hopefully, in your case, both of these will be of highest quality and your flow measurement, condition, or control experience will be an exceptional one!
