Meters & Metering Technologies:
Installation practices for reliable
Meter and AMR / AMI Systems
BY: GARY ZIEGLER, ITRON & SCOTT SMITH, UNITED SYSTEMS
Agenda
• AMR / AMI – QUICK OVERVIEW
• TYPICAL METER INSTALLS,
REMOTE AND PIT SETS
• AMR / AMI MODULE

Overview – The trend is to move from
remotes & touch read to AMR and AMI
Touch Read Generator/ Remote AMR / AMI MXU
Utilities are trending towards AMR & AMI

Reasons a meter cannot be
installed?
1. Bad valve or curb stop is inoperable or
cannot be found
2. Meter is obstructed
3. Bad plumbing
4. Poor premise access
BAD VALVES

Indoor meter locations – Typical
installation
Is the meter accessible?
Does the valve or associated
plumbing appear suspect?
B-box shut off – Replace valve?
Remove old meter; inspect
couplings
Install new meter; turn water on
Mount MXU to floor joist
immediately above meter
location
New meter installations

8
Outdoor meter locations – Typical
installations
Does the lid have hole for MXU? If not, underlid mount MXU per spec
Is the pit flooded / buried?
Is the vault classified as a confined space?
Does valve appear faulty?
Remove old meter; inspect couplings.
Install new meter using new gaskets; turn water on.
Mount MXU thru hole in lid or under lid per mfg suggested method
Typical meter pits

PITS WITH PROBLEMS
PIT IS TOO DEEP PIT IS FLOODED

End Point installation – issues to
consider before starting
Utilities are “Future Proofing” their installs today for migration to AMI tomorrow!
End point compatibility
ROM wire; 2-wire or 3-wire
Integral mount; basement rafter mount; exterior premise mount
Under cast iron pit lid; thru the lid antenna mount; under plastic lid mount.
Does MXU require activation, programming?
Does MXU orientation matter?

AMR / AMI Ready Pit installs
Through-the-lid antenna Under RF-friendly lid
Moving to AMI – Now what?
Prime considerations – Recap
End point mounting location – remote & pit
Encoder compatibility – meter change out required or retrofit?
End point programming required?
Does the encoder need to be reprogrammed?
Software upgrades in place? Hand held computer and head end!
New meter resolution compared to old meter resolution. Truncation
must be correct for accurate billing.

17
Meter Resolution? Why go with higher resolution?
Better Leak Detection.
Better Interval data- data logging.
When retrofitting registers, insure correct size register is installed.
How can different meter resolutions affect billing?
How does resolution affect billing?
Example: Manual Reading and Billing in 1000’s of gallons:
Reading = 1 Billing adds 000 so units billed will be 1,000 gallons.
Higher resolution w AMR: 10 gal =199 or 1 gal =1990 or 1/10th gal = 19900.
Unless truncation codes are used correctly in billing software customer usage
would be: 10 gal =199,000 or 1 gal= 1,990,000 or 1/10th gal = 19,900,000
Customer potentially billed 100x, 1,000x or even 10,000x too much.

What reading is sent to AMR?
AMI Deployment – Step one
Propagation Analysis
Utility identifies all meter locations,
by GPS coordinates or addresses.
Utility identifies all City owned
structures available for antenna
mounting.
Utility provides CIS company so
proper interfaces can be
considered.

AMI Deployment – Tank InstallsTank Equipment Location:
At base of tower?
Outside or inside tank base?
At top of tower?
On railing?
Use Magnetic mount?
Weld new mount during tank resurfacing?
Antenna Cabling?
Cable Size required per mfg? 7/8 Coax?
Cable Routing with secure mounts?
Antenna Separation and Tank Shadowing?
Vertical distance between other existing antenna’s?
Mast required at top of tank to prevent tank shadowing?

AMI Deployment – Pole InstallsPole Availability and Location:
Available Pole Locations?
Existing City/District owned poles?
Existing access to communication pole/tower ?
Fire, Police, School, SCADA, Traffic, Weather siren, etc
Existing JUA light poles?
New JUA required for Poles?
Set new pole or build new tower station?
Power Availability?
Pole equipped with a live Photo Cell?
Short electric run from existing power near by?
No power in area, use Solar?
