Octave – Polymer Ultrasonic Water Meter

OCTAVE – Revolutionary, precise and super reliable ultrasonic bulk water meter.

With superior hydraulic and batteries that last up to 15 years, the Octave is today’s best choice for bulk meters.

The Octave with highly reinforced polymer construction is suitable for “district” uses- from apartment buildings to small neighborhoods/ housing projects.

The reduced weight helps to alleviate pressure on the plumbing systems and helps to prevent distortions.
