The Octave ultrasonic flow meter masters non-revenue water (NRW) and large usage accountability. With a best-in-class turndown ratio as high as 1000:1, the Octave’s wide flow range is among the highest available for any solid-state C&I meter on the market. With FM Approval available on all sizes, the Octave was designed to be the single meter of choice for all of your C&I metering applications including apartment buildings, hospitals, schools, factories, wellheads, and more.

Octave brings the latest in ultrasonic metering technology to Commercial/Industrial (C&I) water meters and puts precise measurement where the real flows exist. An excellent alternative to mechanical compound, single-jet, floating ball, fire-service type and turbine meters, Octave excels at maintaining sustained accuracy for the life of the meter while providing smart AMR capabilities.
