FLO-TRACER™
Tracer dilution flow meter
FLO-TRACER™
The FLO-TRACER™ is a complete and simple-to-use device allowing
measuring a flow in just a few minutes using the tracer dilution
method.
This method consists to inject a quantity of salt into the stream and
to measure its concentration downstream. The result can be
calculated in function of the injected tracer quantity and the
concentration measurements.
The tracing
The measuring probe is placed into the water course. At a sufficiently
large distance upstream so that the tracer mixes perfectly with the
water, a known amount of salt is injected, previously diluted in a
container with the river water (5-20 grams per l/s of estimated flow).
The device records the passing of the tracer and provides the flow
in litres per second immediately at the end of the operation.
