Submetering Installation Guide31.1 OverviewThis document is intended to guide the user through the initial set-up of a WaterGas and Electric Submetering System. The system is made up of usually one ormore PETRC units and up to 600 PET modules.PETRC units are a receiving device that collects information from the PETmodules via Radio Frequencies in the 902 to 928 MHz band and stores thisinformation for later retrival by various “head end” software. The device ispowered by 110 Volts AC and incorporates a 3dBd gain antenna.The PET module is a transmit only device that transmits its consumptioninformation once each 10 to 15 minutes. The consumption information isgathered continuously from any pulse output device including Water, Gas andElectric. The device is for indoor use in a non-condensing environment. The unithas a battery life of greater than 4 years.This document is intended to guide the user through the initial set-up of a WaterGas and Electric Submetering System.

Submetering Installation Guide41.2 FCC Regulatory InformationThis equipment has been tested and found to comply with the limits for a Class Bdigital device, pursuant to part 15 of the FCC Rules. These limits are designedto provide reasonable protection against harmful interference in a residentialinstallation. This equipment generates, uses and can radiate radio frequencyenergy and, if not installed and used in accordance with the instructions, maycause harmful interference to radio communications. However, there is noguarantee that interference will not occur in a particular installation. If thisequipment does cause harmful interference to radio or television reception, whichcan be determined by turning the equipment off and on, the user is encouragedto 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 whichthe receiver is connected.• Consult the dealer or an experienced radio/TV technician for help.This device complies with part 15 of the FCC Rules. Operation is subject to thefollowing two conditions:1. This device may not cause harmful interference, and2. This device must accept any interference received, including interferencethat may cause undesired operation.Service RequirementsThe PET modules and PETRC units have no user serviceable parts.In the event of equipment malfunction, all repairs should be performed by Itron. Itis the responsibility of users requiring service to report the need for service to ourcompany. For service call 1-800-635-5461 and ask for the Customer ServiceDepartment.Caution changes or modifications not expressly approved by Itron, Inc. could voidthe user’s authority to operate this equipment.
Submetering Installation Guide51.3 PurposeThis document is intended to aid installation personnel involved in the installationand operation of the SubMetering network’s PETRC unit and PET module andbecome familiar with the details of the design. This document describes how theunits operates as a system and does not detail the specified limits or theperformance.1.4 ScopeThis document covers the Revision 1 of system hardware. Functional blocks arebroken down into component or group of components and explanations of howthey operate with each other, their inputs and outputs are given.1.5 Basic Components of Itron’s Submetering Network1.5.1 PET ModulesItron’s Meter End Point RF Devices or PET modules encode consumption andtamper information, then transmit this data and other information via RF to thenetwork PETRC units. The PET modules for Electric meters are normallyinstalled under the glass of standard meters and do not require battery power;the Devices for Gas and Water meters are self-contained low-power units,powered by long-life batteries. PET modules can be installed by the metermanufacturer during the manufacturing process or easily retrofitted into mostexisting meters.1.5.2 Network PETRC UnitsThe network PETRC unit receives Water, Electric and Gas usage data via RFfrom the PET modules, and transmits the data to the head-end MV-RS meterreading software via telephone or cellular telephone. Two types of PETRC unitsare utilized in the network: the base PETRC unit and relay PETRC units. Thebase PETRC unit is similar to all other PETRC units except it is equipped with atelephone connection. The telephone connection can be either a standard line ora cellular type.An optional cellular phone interconnect can be utilized on either a temporary orpermanent basis depending on the application. As a temporary option, thevarying lead time of telephone installation can be circumvented by utilizing thecellular phone interconnect option until a cost-effective solution can be installed.In large scale roll-outs, often in areas large enough to span multiple telephonecompanies’ service territories, a single contact within one telephone company isoften not available, which inevitably results in delays. With the cellular telephoneoption, these delays can be eliminated. Additionally, the cellular telephoneoption can be migrated from new installation to new installation as hard-wiredtelephone services are eventually installed at each site.The base PETRC unit is generally mounted at a central point in a apartmentcomplex where ease of interconnection to power and telephone lines areavailable. This base unit can monitor and retain data on up to 600 Water,
Submetering Installation Guide6Electric, and Gas PET modules. All Water, Electric, and Gas usage data isgathered from the PET modules via a Frequency Hopping Spread Spectrum RFtechnology. Having the PET modules utilize a very slow “bubble up” rateminimizes the power consumption of the PET module, thus providing a muchlonger field life. The slow bubble up rate also minimizes unnecessary RFinterference to other users in the RF band.The relay PETRC unit provides a store-and-forward functionality in the network.This unit receives PET module RF transmissions from surrounding PET modules,adds a time stamp, and upon a predetermined time, forwards the stored PETmodule data to other PETRC units (either additional relay PETRC units or thebase PETRC unit). Up to 8 levels can be configured in a string of PETRC units.Each level can communicate with all of the units at lower levels. Thus, thesystem can be configured to provide universal coverage in typical multi-dwellingor high rise environments.The ruggedized PETRC unit (both base and relay) is capable of being mountedoutside and is impervious to weather and potential vandalism.Water, Electric and Gas usage data transmitted by the network PETRC unit viatelephone or cellular telephone is processed by the head-end MV-RS MeterReading Software. The MV-RS system runs on a standard PC. MV-RS not onlyprocesses data received from network PETRC units, it provides an interactive,graphical user interface to allow users to extract and report key information.Itron’s MV-RS Meter Reading Software has been deployed throughout the worldat over hundreds of locations. Originating within the utility market, this Multi-Vendor Reading Software has years of reliable service with millions of metersread. Itron has chosen the MV-RS Meter Reading Software, along with thenetwork PETRC units and the PET modules, as key components in Itron’sSubmetering Network because of their substantial history of reliable operations inthe utility meter reading environment around the world.
