Abstract

Structures and methods are disclosed for measuring fluid flow in an open channel, such as an irrigation channel. By making use of the measures disclosed, a non-intrusive meter, such as an electromagnetic flow meter may be reliably deployed where conventionally a mechanical meter was required, without requiring excess flow conditioning apparatus. The meter may even be made to work reliably under conditions of partial filling.
