Technical Overview

FGS have 18 years of laboratory development and field testing experience at water intakes using underwater acoustics. FGS acoustic fish guidance systems are rapidly becoming the first choice of both plant operators and environmental regulators.

This section provides a scientific overview of how FGS acoustic systems work, are designed to meet site conditions and perform in the field.
