Octave Installation Manual
Chapter 2 –Technical Data
2.1 Measurement Method
The Octave’s measurement method is based on an ultrasonic, transit time, dual-beam sensor which
determines the length of time it takes an ultrasonic sound wave to travel the distance between the two sensors
located in the meter’s body. The two sensors function as both the transmitter and the receiver, each one
alternating these functions so that the ultrasonic wave travels both with and against the direction of the flow.
Ultrasonic waves travel slower against the flow than with the flow, thus the time difference of two waves
traveling with and against the flow leads to determining the velocity and volume of the water.
Note: These sensors are ultra-sensitive; they are not designed to be modified by the user. Any
modifications void warranty on this product.
• The Octave ultrasonic flow meter is a battery-powered, precision flow meter designed for linear,
bidirectional flow measurement of water.
• Flow measurement data is communicated through standard digital pulse or analog output.
• The Octave can be set up for a wide range of applications.

Octave Installation Manual
Chapter 3 –Installation Requirements
3.1 Pre-Installation
Prior to installation check the following:
• Flow rate and volume units are correctly programmed.
• The flow meter is correctly installed per the installation location and position recommendations.
• Output modules are correctly attached.
3.2 Handling of Octave
IMPORTANT:
•DO NOT use chains or wire cable to lift the Octave. To protect the epoxy coating, only
use a nylon lifting strap with appropriate weight capacity.
• DO NOT lift the Octave by the electronic housing unit.
• DO NOT carry the Octave by its lid.
• DO NOT use bolt holes for grip when carrying the Octave.
• DO NOT position the flow meter on its electronic housing unit.
• When bolting the meter to pipe flanges, use washers on both nuts and bolts to
protect the epoxy coating of the Octave.
• When handling the flow meter avoid hard blows, jolts or impact.
3.3 Installation Notes
The measuring tube should be completely full at all times for proper flow measurements. When sensors are not
wet this will show a loss of signal. However, there is no damage when this occurs and the meter will not
measure.
FLOW DIRECTION: The Octave is a bi-directional flow meter. Note the indicating arrow for forward and
backward flows.
Master Meter recommends keeping the lid closed in case of direct sunlight exposure. However, no direct
damage will occur while the lid is open temporarily.
Do not expose the meter to excessive vibration. To prevent this from occurring, support the connection pipe
spools on both ends of the flow meter.
To avoid measuring errors and malfunctioning of the flow meter due to air or an empty pipe, please observe the
following precautions:
• Installation of the flow meter should be at the lowest point of the system, if possible, since air will be
collected at the highest point of a system.
• If possible, maintain positive back pressure in meter outlet piping.
• In order to avoid cavitation, always install control valves downstream of the flow meter and never install the
flow meter on a pump suction side.

Proper Installation: If this is not the highest point in the system or a
hydraulic jump has been installed to keep the flow meter full. The
system has back pressured.
Improper Installation: If this is the highest point in a system or if
pipeline and/or flow meter is subject to being emptied between uses
avoid this installation.

4.3 Volume Display Options
Software Version 3.15 and higher Octaves now offer the ability to choose how volume is measured. If one of
the following icons is not displayed in the box on the bottom right of the display, the Octave software version
is prior to software release 3.15 and flow measurement is in Net Volume.
i. Net Volume (Master Meter Default) –The meter measures both forward and reverse flow. If
backward flow is detected, the totalizer will begin to decrease. If the total is below zero, you
will see a minus (-) symbol on the totalizer.
ii. Forward Flow Only –The meter measures forward flow only. Reverse flow is disregarded.
iii. Alternating Flow –The totalizer will display only forward flow, then toggle to display only
reverse flow. The timing of the how long each measurement is displayed is programmable
with this software version.
4.4 Communication Output Modes
All Octave flow meters are available with one of the optional data output array listed below. This section
describes the visual representation on the register display to determine the communication output mode of
the flow meter.
i. Pulse Output (See Section 4.5) –When the Octave is in Pulse output, this icon will always
be illuminated.
ii. 4-20 mA Output (See Section 4.6) –When the Octave is in 4-20 mA output, this icon will
always be illuminated.
iii. Encoder Output (See Section 4.7) –When the Octave is in encoder output, the wavelength
icon will flash on and off approximately every second.
iv. No Output (See Section 4.8) –When the Octave is not sending a communication signal,
this box will be empty.

4.9 Output Module Installation (Optional)
All Octave water meters are shipped with either a cover plate or communication module installed on the side
of each meter. Even if the meter is not going to be read by radio or some other electronic unit, it is important
to leave one of these devices installed on the Octave to prevent damage to the communication port.
Installing an Octave without a cover plate or communication module would void any warranty.
If you received an Output Module separate from your Octave meter, please follow the steps below to ensure
proper installation of the module. Read through these instructions before attempting to remove the cover
plate. Your module came as a complete installation kit with the supplies shown in Pic. 1.
Octave Output Module Installation Kit
Step 1: Remove the Sealing Cap from the cover plate (Pic. 2).
Step 2: Using the 3mm Allen Key provided, remove the cover plate (Pic.
3). Keep the cover plate and 3mm x 15mm screws for future use. The
communication port is now exposed. (Pic. 4)
Step 3: Place O-Ring around the 4-prong plug of the output module. (Pic.
5 & 6)
Step 4: Insert Output Module into the communication port (Pic. 7), with the
cable pointing down. This will allow the slot inside the communication port to
align with the groove on the module. Do not force the module into the
communication port. This may cause damage to the pins. Secure into place
using the 3mm x 20mm screws provided. Tighten until the screws stop. (Pic.
8)
Step 5: Push the Sealing Cap into the lower screw hole (Pic. 9). Lock the
Sealing Cap in place by firmly pushing in into place or gently tapping it in with
a small hammer.
Note: If at any time the module needs to be removed, take caution not to
allow dirt or water into the communication port. If the module is going to be
removed for an extended period of time, reinstall the cover plate and the 3mm
x 15mm screws.
