ISO 3454:2008 specifies the functional requirements of the equipment, excluding bankside cableway systems, used in the measurement of liquid flow in open channels for sounding (by direct method), and suspending the measuring equipment (for example, current-meter or sediment sampler) at the point of measurement.
Abstract
Overview
ISO 3454:2008 - Hydrometry - Direct depth sounding and suspension equipment defines functional requirements for instruments used in direct depth sounding and for suspending measuring devices (for example, current-meters or sediment samplers) in the measurement of liquid flow in open channels. The standard covers sounding rods, wading rods, sounding lines, cable suspension systems and associated accessories (gauging reels, weights, cranes), but excludes bankside cableway systems. It also includes informative guidance on selecting sinker weights and correcting depth measurements when the sounding line is not vertical.
