Fiberglass Parshall Flumes

Our NSF 61 Parshall Flumes are precision-engineered for accurate liquid measurement in open channels, providing a smooth, uninterrupted flow that prevents debris buildup and ensures reliable performance. Their unbroken flow lines reduce head loss, making them ideal for gravity-fed systems and a wide range of liquid metering applications.

Applications of NSF 61 Parshall Flumes

• Measuring industrial discharges
• Monitoring influent and effluent flows
• Tracking municipal sewer flows

Manufactured using the fiberglass lay-up process, each flume is gel-coated on both interior and exterior surfaces, creating smooth contours that enhance flow consistency and measurement accuracy. Available in throat widths ranging from 1″ to 12′, these flumes can be customized to suit projects of any scale, from small industrial systems to large municipal operations.

Reliable, accurate, and built to last, our NSF 61 Parshall Flumes combine durable fiberglass construction with precise hydraulic engineering, delivering superior performance for every water and wastewater application.
