Standard Test Method for Open-Channel Flow Measurement of Water with Thin-Plate Weirs

Importancia y uso:

5.1 Thin-plate weirs are reliable and simple devices that have the potential for highly accurate flow measurements. With proper selection of the shape of the overflow section a wide range of discharges can be covered; the recommendations in this test method are based on experiments with flow rates from about 0.008 ft ³/s (0.00023 m  ³/s) to about 50 ft ³/s (1.4 m ³/s).

5.2 Thin-plate weirs are particularly suitable for use in water and wastewater without significant amounts of solids and in locations where a head loss is affordable.
