Overview

ISO 9555-3:1992 - "Measurement of liquid flow in open channels - Tracer dilution methods for the measurement of steady flow - Part 3: Chemical tracers" - specifies the use of chemical tracers (for example iodide, lithium, chloride, chromium) for discharge measurement in open channels using tracer-dilution methods. It complements ISO 9555-1 (general principles) and addresses tracer selection, field and laboratory measurement techniques, sampling, injection methods, environmental influences and sources of error for steady (and slowly varying) flows.

Key topics

Tracers covered: common chemical tracers (iodide, lithium, chloride, chromium) and notes on other possible tracers (bromide, fluoride, manganese sulfate, nitrate).

Measurement principles: constant-rate injection and integration (sudden injection) approaches as applied to chemical tracers (reference ISO 9555-1 for general procedures).

Analytical methods:

Catalytic spectrophotometry and ion-selective electrodes for iodide.
Flame atomic absorption/emission techniques and other laboratory analyses for lithium and chromium; calorimetric methods for hexavalent chromium with options for sample reconcentration to improve detection limits.
Conductivity method commonly used for chloride (sodium chloride) in the field.

Field vs laboratory: guidance on in-situ measurement (e.g., ion-selective electrodes, conductivity meters) and laboratory assays that may require dilution or reconcentration of samples.

Environmental factors: chemical (interferences), physical (mixing, solubility, density segregation), and biological influences that affect tracer behaviour and measurement accuracy.

Injection & sampling techniques: recommended approaches to ensure homogeneous mixing and representative sampling.

Error sources & quality control: background concentrations, matrix effects (colour, turbidity), electrode interferences, calibration needs and steps to minimise contamination and analytical bias.

Special requirements: handling, toxicity and storage considerations for specific tracers.

Applications and users

Practical for hydrologists, environmental engineers, water resource managers, field technicians and analytical laboratories conducting discharge measurements of rivers, streams, canals and industrial effluents.

Useful where conventional flow metering is impractical (complex cross-sections, turbulent or unsteady conditions, flood events) or where non-invasive tracer dilution yields safer, reliable estimates.

Applicable to studies requiring trace-level detection, budgeted tracer use, or when site-specific background conductivity/chemistry requires custom calibration.
