IS 15454 : 2004 Liquid Flow Measurement in Open Channels - Velocity-area Method Using a Restricted Number of Verticals

1 Scope

1.1 This standard describes a velocity-area method which can becarried out using three verticals only, without significant loss ofaccuracy, and gives advice on when such a `short-cut' method shouldbe used.

1.2 The method specified in this standard is not an alternativeto the velocity-area method specified in IS 1192, which givesaccurate results and should be used under normal conditions. Thisshort-cut method has a limited field of application and is intendedfor use only in special circumstances as indicated in 7.
