1.13 Performance of the flow meter
•
Uncertainty over measured speed: up to ±0.5 %.
•
Repeatability: up to 0.1 %.
•
Linearity: up to 0.1 %.
•
Typical uncertainty on the flow rate calculation: from 0.5 to 5 % depending on the application and
the number of chords.
Important: The accuracy of the measurement also depends on the accuracy with which the geometry of
the measuring point is measured, the dimensions of the probe pairs, the distance between the probes and
the length the wave has to travel between two probes. An inaccuracy on one of these values may
compromise the accuracy of the measurement.
1.14 Cleaning the flow meter
The box may be cleaned with water, diluted alcohol or detergent using a sponge or a soft cloth. Do not use
abrasive materials or solvents.
1.15 Recycling the flow meter
In the context of decree no. 2005-829 dated 20 July 2005 and decree no. 2009-1139 dated 22 September
2009 relating to the collection, treatment and disposal of electrical and electronic equipment, batteries and
