We get it: we write a lot of content on a lot of different topics and coming up with content and relevant topics is time comsuming. For our competitors, it can be hard to keep up! It's the reason why we see our topics used and content parroted. But take a further look and you'll…

When using a flume to measure pipe flow, the incoming pipe slope is a critical factor. Too great a slope and the flow into the flume will be too energetic and the flume won't produce accurate results.

Fiberglass Flow Metering Manholes from Openchannelflow are a great solution to the problem of needing to measuring below ground flows. The manholes are light weight, corrosion resistant, watertight, and come with flume, weir, or mag meter already factory integrated.

It's a common for a treatment system operator need to measure the flow of sewage in a wastewater collection system. These flows are below grade and are usually under open channel (non-full pipe) conditions. In some cases, existing manholes or vaults can be used. Into these a…

Most of the flume styles currently used to measure the flow of water in non-full pipes were not originally conceived to handle such flows. While engineered transitions – end adapters – have been developed for some of these flumes, many installations have site-formed…

Openchannelflow is pleased to announce that it has entered into agreement with The Spectrum Group, Inc. of Metairie, LA for full-line promotion and representation announces in the States of Louisiana and Mississippi.

For a flume to operate correctly, the approaching flows must be subcritical and well developed. Sometimes, however, the approaching flow has high velocity or is turbulent due to steep pipe slopes or pumped flow. To control and condition these flows, Openchannelflow offers Energy…

It is with great pleasure that Openchannelflow announces that M.L. Johnson Co. of Cincinnati, OH has signed as a full-line representative of Openchannelflow for the Midwest.

Publically owned wastewater treatment plants (POTWs) collect wastewater from homes, commercial and industrial facilities and remove harmful organisms and other pollutants so that the treated water can be returned to the environment without impact the receiving waters. As part of…

While we frequently talk of the advantages that flumes have over weirs, weirs in general (and weir boxes in particular) can be well suited to measuring flows on unusual pipe configurations. Without considerable flow conditioning, flumes require the approaching flow to be centered…

Openchannelflow is please to annouce that LRM, Inc. of Souderton, PA has agreed to act as Openchannelflow's exclusive representative for eastern Pennsylvania, Maryland, and Delaware. LRM promotes leading manufacturers in their territory, including: Endress + Hauser, ProMinent…

Covers are used over flumes and weir boxes for a number of different reasons: eliminating inflow, aesthetics, operator safety, foam, sensor protection, or containing foaming / splashing flows. To meet these applications, Openchannelflow offers solid and transparent covers in both…

It is with great pleasure that Openchannelflow announces that PCS Pump and Process of Fairfield, NJ has signed as a full-line representative of Openchannelflow for the New York / New Jersery area. PCS represents leading manufacturers like Endress + Hauser, Mission Communications,…

When comparing flumes from different companies ask one simple question first:

We are frequently asked if a stilling well can or should be used on a flume at the headworks of a wastewater treatment plant (WWTP). The answer is: no, a stilling well should NOT be used at a headworks – even if the flow conditions are turbulent.

Over time a primary device’s (flume or weir) staff gauge may need to be replaced. Wear, vandalism, nature of the flow stream, and device construction can all play parts in a gauge needing to be replaced. When replacing a gauge there are two styles available: adhesive gauges and…

Wing walls are nothing more that flat (typically) walls that extend from the channel banks to the flume. Their purpose is to direct flow into the flume in a controlled manner.

The 60-inch Parshall Flume is a large flume, usually shipped in two pieces, that is primarily used to measure flows for water rights and watershed measurement as well as at sewage treatment plants. The 60-inch Parshall Flume is useful in a number of applications:

The Large 60º V Trapezoidal flume is one of the original Trapezoidal flumed developed. The flume has good low-end resolution, while the v-shaped cross section allows for larger flow rates to be measured with reasonable head. Solids passage is good with the flume having a flat…

A Weir Box is simply a fabricated box or vault which incorporates a weir plate to measure the flow of piped water. Weir boxes work best when measuring flows from about 10 gpm to 500 gpm. Lower than that and accuracy falls off rapidly. Higher than that and the weir box becomes…
