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.

Description

(57) 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.
