OPERATION
• The Octave's measurement method is based on an ultrasonic, transit-time, dual-beam sensors that determines 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.
• The Octave is a battery-powered precision water meter designed for linear, bidirectional flow measurement of water.
• Flow measurement values can be transferred through an output module.
• The Octave display can be set up for a wide range of outputs.

HANDLING THE WATER METER
Important handling Information:
• Do not lift the Octave by the electronic housing.
• Do not carry the Octave by the lid.
• Do not place the Octave on the electronic housing.
• When handling the Octave, avoid hard blows, jolts or impacts.

INSTALLATION EXAMPLES FOR ACHIEVING TOP PERFORMANCE
The following examples are recommendations for achieving top performance.
Two (2) diameters of straight pipe are required when installing a 90° elbow before or after the meter. (See Figure 1)
Two (2) diameters of straight pipe are required when installing the meter upstream or downstream of a valve, tee
connection or other source of significant turbulence. (See Figures 2 and 3)
NOTE: The installation of the meter upstream of a pump or large valve is not recommended due to potential
cavitation issues.
Five (5) diameters of straight pipe downstream of a pump (before the meter) and Two (2) diameters of straight pipe
downstream of the meter are required. (See Figure 4)
NOTE: When the meter is downstream of the pump, Netafim recommends additional straight pipe to ensure
accurate measurements.
Meter can be installed horizontally or vertically with the water flowing up. It is not recommended for installation
where the direction of flow is below the horizontal plane. (See Figure 5)
To eliminate air in the pipeline and maintain accuracy, use of and proper placement of Continuous Acting Air Vents
is required. We require a Combination Air/Vacuum Release Air Vent or the Pro Air Vent.
Recommended Air Vent placement: 3” and 4” meters place air vent 12” to 18” before the meter; 6” and 8” meters
place the air vent 18” to 24” before the meter; 10” and 12” meters place the air vent 30” to 36” before the meter.
Installing a Check Valve downstream of the meter creates back pressure to aid in the meter filling with water.
INSTALLATION
NOTE:
Air Vents can be placed on a
6” to 12” riser for evacuation
of a larger volume of air.

INSTALLATION
INSTALLATION NOTES
• For proper flow measurement, the Octave’s measuring chamber should be completely full at all times. Non-wetted
sensors show loss of signal. Though this will not cause damage to the meter, it will however, not measure flow and
display zero.
• Flow direction: the Octave is a bidirectional water meter. Note the indicating arrow on the Octave display for forward
and backward flow.
• Leave the lid closed except when reading the meter.
• Do not expose the Octave to excessive vibration. To avoid vibration, support the pipeline on both sides of the meter.
• To avoid measuring errors due to air in the flow tube, observe the following precautions:
- Since air collects at the highest point in the system, installation of the water meter should be at the lowest point
- Always install control valves downstream of the meter in order to avoid cavitation
- Never install the meter on a pump suction side in order to avoid cavitation
PIPE FLANGES
• Refer to the standard dimensional drawings for flange spacing, accommodating for the thickness of gaskets.
• Install meter inline with the pipe axis. The pipe flange faces must be parallel to each other.
• Permissible length deviation: Lmax - Lmin 0.5mm (0.02”).
START-UP
• Check that the meter has been installed correctly.
• Check that the flow rate and volume units are correctly pre-programmed on the display.
• Check that the output module is correctly attached.

HARDWARE VERSIONS
There are now two different hardware versions for the Octave Water Meter. Version 3 was for Octave Water Meters
manufactured prior to June 2017 and Version 4 for all Octave Water Meters currently available. Version 4 adds
additional measuring units, water temperature, pulse output resolution and a sleep mode to the LCD.
