FCC Notice
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
RF Exposure Information
This equipment complies with the FCC RF radiation requirements for uncontrolled environments. To maintain
compliance with these requirements, the antenna and any radiating elements should be installed to ensure that
a minimum separation distance of 20cm is maintained from the general population.
Professional Installation
In accordance with section 15.203 of the FCC rules and regulations, the MIU must be professionally installed
by trained utility meter installers. Changes or modifications not expressly approved by the party responsible for
compliance void the user's authority to operate the equipment.
Changes or modifications not expressly approved by the party responsible for compliance void the
user's authority to operate the equipment.

Industry Canada
This Class B digital apparatus meets all requirements of the Canadian Interference Causing Equipment
Regulations. Operation is subject to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Cet appareillage numérique de la classe B répond à toutes les exigences de l'interférence canadienne causant
des règlements d'équipement. L'opération est sujette aux deux conditions suivantes: (1) ce dispositif peut ne
pas causer l'interférence nocive, et (2) ce dispositif doit accepter n'importe quelle interférence reçue, y compris
l'interférence qui peut causer l'opération peu désirée.

MACH 10 Residential Ultrasonic Meter Installation and Maintenance Guide 1
1 Product Description
This chapter provides a general description of the Neptune MACH 10®Ultrasonic Meter
(subsequently referred to as the MACH 10).
Introduction
The MACH 10 solid state meter uses ultrasonic technology and solid state electronics.
The meter is contained in a compact, totally encapsulated, weatherproof, and ultra violet
(UV) resistant housing for residential and light commercial applications. Ultrasonic
technology features:
• Contains no moving parts
• Provides long-term accuracy
• Eliminates measurement errors due to sand, suspended particles, and pressure
fluctuations
The MACH 10 provides a Neptune E-Coder®PLUS output signal to Neptune R900®,
R450™, and other AMR/AMI endpoints. The MACH 10®)R900i™ contains a MACH 10
meter and an integrated R900 radio for transmitting meter reading data. The
MACH 10®)R450i™ contains a MACH 10 meter and an integrated R450 radio for
transmitting meter reading data.
The meter electronics and battery are permanently sealed to eliminate the intrusion of
moisture, dirt, or other contaminants. It is suitable for installation in all environments,
including meter pits subject to continuous submergence.
The MACH 10 meter can be installed using horizontal or vertical piping with no straight
pipe requirements before or after the meter.

Product Description
Advantages of the MACH 10
The MACH 10 offers the following advantages over traditional
mechanical technologies.
• Extended measuring range
• High accuracy sustained over the meter's life
• High repeatability
• High durability
• Minimal intrusion in the flow stream
• Unaffected by particles in the water
• Bidirectional flow capable
• Free of maintenance
Understanding Ultrasonic Technology
An ultrasonic water meter uses technology to measure the velocity of an
acoustically-conductive liquid moving through it. The velocity of the
water is then converted to volume throughput using sophisticated
algorithms and electronics. The MACH 10 utilizes transit-time
ultrasonic technology.
Transit-Time Technology
Transit-time technology takes advantage of the principle that an
acoustic signal travels faster with the flow than against the flow. These
meters have a pair of transducers that are essentially transceivers,
sending and receiving the acoustic signals.

Transducer 1 Transducer 2

MACH 10 Residential Ultrasonic Meter Installation and Maintenance Guide 3
Product Description
The transducer on the upstream side of the meter generates an acoustic
signal that travels through the pipe along a predetermined path.
Figure 3 Transducer - Upstream
The downstream transducer receives the signal, and the meter calculates
how long it took to travel from one transducer to the other. This is
referred to as t1or time-down.
Figure 4 Transducer - Downstream
Next, the downstream transducer generates a signal that travels
upstream along the same predetermined path. This is referred to as t2or
time-up.

Product Description
The signal is received by the upstream transducer and the meter
calculates how long it took to travel in the upstream direction. The
difference between the downstream and upstream transit time is
proportional to the flow rate.
The calculated velocity of the water is then converted to volume based
on the meter size (pipe diameter) and by the algorithms and electronics
in the register head and displayed on the liquid crystal display (LCD).
Figure 6 Transducer - Calculated Velocity
Transducers
In ultrasonic flow meters, high frequency sound waves are generated by
applying a small voltage to the piezoelectric transducer in the meter.
The opposite also occurs: an ultrasonic signal received by the
transducer is converted to an electrical signal.
The transducer is simply a device that converts one type of energy to
another. In this case, it converts the electrical energy to acoustical
energy and vice versa. The actual frequency of the ultrasonic signal is
determined by the characteristics of the transducer used in the specific
application.
The ultrasonic signal propagates at the speed of sound. But the speed of
sound is variable and depends on the medium through which it is
traveling and the temperature of that medium. Therefore, ultrasonic
meters are calibrated for a specific liquid and temperature range.

Product Description
Summary
The Neptune MACH 10 meter is a transit-time ultrasonic flow meter
with wetted transducers. Designed as an alternative for small
mechanical meters, the MACH 10 meter utilizes traditional utility pipe
connectors and lay lengths. It is totally self-contained. The battery,
processor circuit, and electronic display are fully potted and
permanently sealed as an integral unit. The MACH 10 meter provides
an E-CoderPLUS output signal to Neptune R900, R450, and other
AMR/AMI endpoints. The MACH 10)R900icontains a MACH 10
meter and an integrated R900 radio for transmitting meter reading data.
See Figure 18 on page 27. The MACH 10)R450icontains a MACH 10
meter and an integrated R450 radio for transmitting meter reading data.
