Full title and description

St ISO 3454-2008 — Hydrometry — Direct depth sounding and suspension equipment. This International Standard specifies the functional requirements for equipment used to obtain direct depth soundings and to suspend measuring instruments (for example current-meters or sediment samplers) at measurement points in open-channel flow; bankside cableway systems are excluded from the scope.

Abstract

ISO 3454:2008 sets out functional requirements for depth-sounding and suspension equipment used in the measurement of liquid flow in open channels. It covers devices and arrangements for making direct depth soundings and for suspending measuring instruments at the point of measurement, with an emphasis on performance and suitability for hydrometric field use. Bankside cableway systems are explicitly excluded.

Scope

The standard applies to equipment used for making direct depth soundings and for suspending measuring instruments at the point of measurement in open channels (rivers, streams and artificial channels). It specifies functional requirements for that equipment but excludes bankside cableway systems. The intention is to ensure that sounding and suspension equipment are suitable for reliable hydrometric measurements in the field.

Key topics and requirements

• Functional requirements for direct depth-sounding equipment (design intent and performance for reliable depth measurement).
• Functional requirements for suspension equipment used to position and hold instruments (e.g., current-meters, sediment samplers) at measurement points.
• Explicit exclusion of bankside cableway systems from the document’s scope.
• Requirements intended to support accuracy, repeatability and field suitability of hydrometric measurements in open channels.

Typical use and users

Used by hydrologists, water-resources engineers, field technicians, environmental agencies and laboratories involved in measurement of liquid flow in open channels. Typical applications include routine gauging, research measurements, and deployments where point-depth and instrument suspension need standardised functional performance.

Related standards

ISO 3454:2008 is part of the ISO hydrometry work programme (ISO/TC 113). Related documents addressing complementary aspects of open-channel flow measurement include ISO 3455 (Calibration of current‑meters in straight open tanks) and other ISO hydrometry standards that cover stage–discharge relations, field discharge measurement methods and instrument calibration.
