Octave® Ultrasonic Water Meters

Octave® Ultrasonic Water Meters have a ± 1.5% accuracy for nominal flow rates. The vacuum sealed and tamper proof register provides durability and long-term performance. A multi-line digital readout display provides immediate reporting and visual indicators for critical conditions. Lithium batteries provide a 10 year life expectancy. Octave also offers a 5 year pro-rated warranty – the industry’s longest.

Why WST Series Water Meters

  • Double-beam ultrasonic sensors provide highly accurate flow data and reliable operation.
  • No impeller or moving parts in the flow path provides for unrestricted, low pressure loss flows.
  • Reduced maintenance of wear-prone parts commonly found in other meters.
  • Flow ranges from <1 GPM to 5,500 GPM.
  • Multi-line readout screen provides complete flow and volume information along with:
    • Leak detection
    • Flow direction
    • Output mode
    • Battery level
    • Alarms and errors
    • Active communication mode
  • Vacuum sealed and tamper proof IP68 register provides durability and long-term performance.
  • Lithium batteries provide a 10 year life expectancy.

Product Advantages

  • Each meter has a unique, unalterable bar-coded serial number for identification.
  • Standard registers are programmed to log and display both forward and reverse flow. Physically reversing the meter will not decrease the forward flow totalizer.
  • Each meter ships with a certificate verifying flow accuracy with a ± 1.5% accuracy for nominal flow rates.

HOW OCTAVE WORKS

The Octave’s measurement method is based on an ultrasonic, transit-time, dual-beam sensors that determine the length of time it takes an ultrasonic wave to travel the distance between the two sensors located in the meter’s body. The sensors function as both sender and receiver, each one alternating these functions so that the ultrasonic wave travels both with and against the direction of the flow. Because the ultrasonic wave travels slower against the flow than with the flow, the time difference of the two waves allows the meter to determine the flow rate.

Octave Programming and Digital Display

Multi-line digital LCD readout display provides immediate reporting and visual indicators for critical conditions. The 9 digit display is easy to read at a glance.
Each Octave Meter will be pre-programmed before shipment for an instantaneous flow rate in Gallons per Minute (GPM) and the specified user’s requirements for:

  • Volume Totalizer Units (Gallons or Acre-Feet)
  • Output Resolution for Optional Pulsed Output

NOTE: Programming software is not available to the end user. Once the meter is programmed by the Netafim prior to shipment, it can only be reset by Netafim. When changing between totalizer options (US Gallons to Acre Feet), the totalizer memory can not be reset so vital data will not be lost.
