“Until now we have set up 13 Octaves. Since the beginning of sectorization, in 2012, we have no problems to report. We are very happy with our decision. Octave, it’s the best!”

(Jean-François LAILHEUGUES, Purchasing Manager and Head of the SIAEP Marseillon Sectorization Project)

To solve the problem of sectorization, the SIAEP installed 13 Octaves and SOFREL communication modules (LS42 and LS500) throughout the area.
The objective was to:
• Become familiar with the operation of the water network
• Check for leaks

They did a comparison between Electromagnetic Flowmeters and the Octave, which led to the conclusion that Octave is the better meter to install.
