BS 3680-2D is an international standard that discusses the measurement of liquid flow in open channels. BS 3680-2D deals with the use of fluorescent tracers in discharge measurements by the dilution method.
Apparatus and methods of widespread application are set out in ISO 9555-1 and BS 3680-2D don’t repeat them, except for those relating specifically to fluorescent tracers. The use of fluorescent tracers is attractive because of the insignificant amounts of tracer needed to make a discharge measurement. Certain fluorescent tracers are measured at concentrations of less than 1 4g/l. Fluorescent tracers are easy to handle, and their concentrations are readily determined.
BS 3680-2D on measurement using fluorescent tracers is relevant to:
The dilution method is a method in which the discharge is deduced by determining the ratio of the concentration of the tracer injected to that of the tracer at the sampling cross-section. A tracer is an ion, compound, or radionuclide introduced into a flow system to follow the behaviour of some component of that system.
BS 3680-2D discusses definitions that depict a user-friendly idea of fluorescent tracers. BS 3680-2D has enabled the unnecessary repetition of text of the various parts to be avoided and proved to be a more convenient form of presentation for the user. BS 3680-2D assists with the tracer measurement. BS 3680-2D also assists with techniques for tracer injection which contributes to the performance characteristics of fluorescent tracers ensuring their reliability.
Overall, BS 3680-2D is useful as it provides guidance on the measurement of liquid flow in open channels that can be beneficial for your business and can also help you to expand your business globally.
