| Canal Palmer Bowlus |
Palmer Bowlus Flumes: The Palmer Bowlus metering flume has been widely used since 1937 for measuring water and wastewater in open channels or pipelines that are not under pressure. Some of its most important characteristics include measurement accuracy, low head loss, minimum flow restriction and ease of installation in pipelines. |
|
The Palmer Bowlus is normally installed in
a "U" shaped channel fed by a pipeline such as storm drains
and sewers. This convenient flume requires little redesign or special
modification of circular conduits for installation. |
| Accuracy |
The accuracy of the Palmer Bowlus
flumes is comparable to that of Parshall or other types of Venturi flumes.
Experiments indicate that within the normal range of flows (from under
10% to 90% of flume capacity), measurement accuracy is usually within
+/- 3% of flow rate. |

| Low Flow Flumes | |
| Low Flow flumes are a proprietary flume, unique
to Accura-FloTM. The "Low Flow" is a variation of the Palmer Bowlus
flume. It was developed to give improved resolution of low flow in circular
conduits. Options: • Sectional designs for limited access • 2D & 4D channel options • Channel inserts • Stilling wells • Staff gauges • Wide variety of instrument accessories |
