Description

These two types of adjustable sluice gate, undershot and overshot are widely used for the control of water in canal systems.

In the absence of more accurate devices they may be used for the approximation of flow rates.

Armfield sluice gates are made from stainless steel and plastic and are designed to fit in a rectangular channel section 0.450m wide.

Two types are available – Undershot (FEX40-3) and Overshot (FEX40-4).

History

In a surface irrigation distribution network it is necessary to establish a command from which water may be discharged to the area where it will be applied to growing crops. Regulation of discharge, its distribution and disposal is carried out using a range of control structures selected to suit particular situations.

In order to familiarise technicians with the mode of operation of a variety of control structures, Armfield has designed and produced a range of demonstration units.
