Dye Dilution for Both Open and Closed Water Applications
What is Dye Dilution?
The dye dilution method for measuring flow is a method that allows an instantaneous flow to be measured by determining the dilution of a tracer injected into a flow. The dye dilution method is based on a mass balance calculation. A small quantity of fluorescent dye at high concentration is continuously injected at a measured, constant rate into the test flow. Concentration of the fully mixed flow is determined by fluorescence intensity measurements. The ratio of the injected concentration to the final concentration, minus any background concentration in the incoming flow, multiplied by the injection flow equals the fully mixed test flow.
