Open-Channel/Partially Full Pipe Meters
Flow Meters for Full-Pressurized Pipe Flow
Flumes are specially shaped, engineered structures that are used to measure the flow of water in open channels. We provide all of the common types and sizes of flumes in fiberglass, aluminum, and galvanized steel. Flumes can be customized with inlet/outlet adapters, wing-walls, stilling wells, staff gauges and probe wells.

Weirs are common and simple methods of measuring the flow of water in open channels. At its simplest, a weir is no more than an obstruction placed in a channel over which water flows (unlike flumes where the water flows through the structure). Often this flow is over a specially shaped notch or opening set above the floor of the channel.
Properly sized, built, and maintained, a weir can provide inexpensive and accurate flow measurements.

Packaged Metering Manholes
Fiberglass Packaged Metering Manholes (PMMs) solve the difficult problem of how to measure piped flows below grade. Starting with our industry leading fiberglass manhole tube, Openchannelflow integrates: a flow device (flume, weir, or mag meter), cover, base, and access ladder.
The result is a single-piece, watertight, and corrosion resistant structure from which operators can accurately (and safely) measure and sample flows. For additional information: https://www.openchannelflow.com/manholes
