Dependent on application
Sensors in close proximity to one another
– Well suited to low power radio
– Fixed or mobile network
Sensors spread over distance
– High power radio
– GPRS
Reading methods dependent on
– Meter density
– Data requirements
– Reading frequency
No One Solution?

Remote Reading – A Utility Journey
Available remote valve actuation and in-home displays,
true AMI in every aspect
Proven, mature wireless communications protocol for
ultra low power consumption and long range capabilities
The core of any AMI, two – way communications empowers
utilities with full control over meter management
Allows utilities to be proactive instead of reactive
to customer service concernsMust be Designed for 10+ years of useThe solution for comprehensive meter system management
Enables utilities to migrate to fixed network AMI or
to deploy a hybrid system for rural settings
Two – Way Communications
Automatic, Real Time Alarms
Fixed Network AMI
Long Battery Life
Drive – by AMR
Advanced, Industry Leading Functionality
Full 2 wayTechnology
(FlexNet)
Walk – by AMR
Allows utilities to implement an AMR System at their own pace
with a migration strategy to AMI when ready
AMR/AMI
4
Ideal for:
– Pilot systems
– High revenue meters
– Industrial
– Difficult to read
– Mixed population of automated and non automated
Generally used where:
– There are a relatively small percentage of AMR meters
– Larger population of AMR meters with high density installation
– Long distance between automated meters
Reading technology options:
– 2 Way – polled radio
– 1.5 Way – LAT
System Application – Walk By
5
Ideal for:
– Larger installed base
– Wider geographical spread
Generally used where:
– All meters (in an area) are automated
– No visual/manual read required
– Greater distance between meters
Reading technology options:
– 1 Way – Broadcast radio
– 1.5 Way – LAT
System Application – Drive By
6
Ideal for:
– Very large installed base
– 100% automated (by city or area)
– High labour costs – meter readers
– Increased data requirements
Generally used where:
– Utility is already experienced in AMR
– Frequent reads required
– Very high meter population
– Meters not accessible
Reading technology options:
– 2 Way – polled radio
– 1.5 Way – LAT
System Application – Fixed Network

Decision based on:
– Business case• Labour cost
• Water cost
– System objectives• Enhanced read & bill
• Leakage
– Budget
Which technology?
– To suit your environment
– How many meters?
Mobile
– Fast/flexible but still requires people
Fixed
– Fully intelligent but expensive
Consider migration path

Short Message Transmit
– Each 15 seconds
Open Receiving Port
– Each 4th transmission
OMS
– wMBus T1
– Transmission each 60 minutes
OMS message limited by the standard EN 13757-4

Short Message Transmit
– Each 5 minutes
Open Receiving Port
– Each 4th transmission
OMS
– wMBus T1
– Transmission each 30 seconds
Sensus OMS Configuration
21
OMS/wMBus – True Interoperability
22
Open Metering Standard (OMS)
– wMBus
Widely used in Europe
– Multi Utility applications
Driven by Standard EN 13757-4
– Previously only included 868MHz
– 433MHz added to the standard in 2013
Many equipment manufacturers produce hardware to transmit &
read in 868MHz
Manufacturers taking time to catch up with 433MHz
Several meter manufacturers now use OMS/wMBus in 433MHz
– Sensus, Hydrometer, Kamstrup, Zenner
OMS Compatibility
23
The case is compelling
– Cost of water/labour
– Customer service issues
– Added value
Key barrier to adoption:
– Proprietary systems
Sensus solution:
– 2nd OMS embedded radio with T1 mode broadcasting
settings (unidirectional) installed in every unit by default
– Read by MUCs and any other OMS compatible device
specified by the market for the European smart
metering program
Sensus solution:
– Open DLL’s
– Share libraries with developers
Protecting Your Investment

Configuration:
– iPERL static water end point
– RF on Drive by
8000 smart water meters in
Faulquemont, North eastern France
SEBVF is made up of a group of
84 municipalities, 670 km of water
networks
Challenges:
– Difficulties in reading hard-to-reach meters
over a large geographical area
– Improve metrology on low flows
– Comply with French regulations
– Educate their end customers on water
consumption
SEBVF Smart Water Solution
Key Takeaways:
Meter readings increased from 400 to
3,000 per day giving SEBVF:• Understanding of end customer usage
• Rapid detection of leakages
