Theory of Operation
C&I Gas Meter Interface Purpose
The C&I Gas Meter Interface is a programmable end-point device, designed to replace or supplement a customer’s
existing mechanical utility meter index. Using a magnetic pulse output adapter to interface to the meter output, it can
be installed on a variety of meter brands.
The C&I Gas Meter Interface end-point device allows for accurate, near-real-time customer utility use information,
which can be read from a remote location.
Functionality
The C&I Gas Meter Interface end-point device performs two basic functions:
• Gathering and recording customer utility use information directly at the metering point.
• Sending and receiving messages to and from the utility company computer system such as:
- Utility use, status, alarm data, and similar information.
- Data requests, configuration, and verification messages.
C&I Gas Meter Interface end-point devices communicate with the utility company computer system using a
combination of Local Area Networks (LAN), AxisGateTM nodes, and a Wide Area Network (WAN).
Components
C&I Gas Meter Interfaces are Silver Spring Networks end-point devices, containing two primary components: a
digital processor and a radio transceiver.
The digital processor within the end-point device gathers and records utility use data at the metering point. Every time
the meter drive rotates, pulses are recorded by the digital processor. The pulses are converted into utility use data, and
this data is stored until readings are requested from the utility.
Each C&I Gas Meter Interface also contains a 900MHz two-way radio frequency (RF) transceiver. This radio
provides communication between the end-point device, and an AxisGateTM node. Depending upon the communication
distance involved, and Silver Spring Networks relay might be used between the end-point device and the node, to
extend RF communications. This RF connection between the end-point device and the node, possibly through a relay,
is a Local Area Network (LAN).
AxisGateTM nodes then communicate with the rest of the AxisPathTM network using a Wide Area Network (WAN).
This communication allows C&I Gas Meter Interfaces to transmit use data to the utility, or to receive requests or
programming instructions from the utility, or from a technician or installer using a Field Service Unit attached to a
laptop computer.
See Silver Spring Networks publication 98-00004 (System Summary) for a more detailed explanation of
communications on the Local Area Network (LAN) and Wide Area Network (WAN).

Installation and Initialization
Introduction
This section includes a set of detailed procedures for installation, configuration, and testing.
CAUTION
Read and study the following safety information before you
proceed with installation. In addition, cautions and warnings
appear within procedures and throughout the test, where
appropriate, to remind you of any related safety information.
Safety Information
• Observe the following safety guidelines. Careful planning of every job is essential. Nothing should be taken for
granted. Do not take chances!
• Read and follow all approved policies and procedures provided by your employer associated with the procedures
in this manual.
• Keep the work area clean and dry. Cluttered work areas cause accidents and injuries.
• Provide good lighting in the work area. You cannot work safely if you cannot see what you are doing.
• Report unsafe conditions or defective equipment to your immediate supervisor.
• Select the right tool for the job. Use tools properly. Keep tools in good working order.
• Handle materials carefully. Lift and carry properly.
• Keep unauthorized people out of the work area. Be especially cautious of children, who tend to be drawn to work
activity.
• Silver Spring Networks Inc. assumes no liability for the customer’s failure to follow these safety guidelines.
Equipment Needs
This section lists, and briefly describes, the various pieces of equipment required for C&I Gas Meter Interface end-
point device installation, initialization, and testing processes.
• Laptop computer-Runs the FSA software, which stores and retrieves work order information, and configures and
tests installed C&I Gas Meter Interfaces.
• Field Service Unit-900 MHz two-way radio frequency (RF) transceiver, allowing communication with an IMU for
initialization.’
Before Installation
Field Service Unit Set-Up
The Field Service Unit is a 900 MHz two-way radio frequency (RF) transceiver, used for configuring and
testing Silver Spring devices.
Applicant: Silver Spring Networks, Inc. Gas Pulse Interface FCC ID:OWS-963
After arriving at the customer site, activate and test the Field Service Unit as follows:
CAUTION
DO NOT turn the Field Service Unit ON if
the antenna is not installed. Damage to
the Field Service Unit will result.
1. Plug the Field Service Unit connection cord into the serial port of the laptop computer.
2. Plug a 9 VDC / 500 mA power supply into the Field Service Unit power socket.
CAUTION
Using anything other than a 9 VDC /
500 mA power source may damage the
Field Service Unit.
3. Turn on the Field Service Unit. An indicator light will shine if the
Field Service Unit power supply is functioning correctly.
Installation Procedure
1. Remove index register from C&I gas meter. For American, Rockwell and Sprague meters, remove the index
register and replace with the Pulsimatic pulse output register or the RioTronics index register with pulse output.
For a Roots meter interface, attach the appropriately modified register head with pulse output to the meter before
installing the pulse output pickup device.
2. Attach the Silver Spring Networks C&I Gas Meter Interface (p/n 1620-05001) to a surrounding fixture to the gas
meter. Fixturing locations can include the meter piping, meter fixturing brackets or surrounding structures.
3. Attach the cable assembly from the Pulsimatic or RioTronics pulse output generator to the Silver Spring Networks
C&I Gas Meter Interface (p/n 1620-05001). The cable assembly attaches with a ‘push and twist’ lock for the
weather-resistant seal.
Start the Field Service Application
Note
See Silver Spring Networks publication 98-00001 (Field Service Application User’s Guide) for a more detailed
explanation of FSA operation.
1. Turn on the laptop computer.
2. Launch the FSA software. No error messages will display if the connection between the computer and the Field
Service Unit is working.
3. Log in to the Field Service Application.
Install the Pulse Output Interface Device
For American/Sprague and Rockwell meters, interface with either the Pulsimatic pulse output adapter or the
RioTronics adapter.
• Install the Pulsimatic unit in line with the index register and upon installation of the unit, replace the index register
on top of the Pulsimatic.
• Install the RioTronics-enabled index register in place of the existing index register.
For Dresser Industries’ Roots meters, please follow the instructions for installation of the RioTronics Interface module.
Install the Silver Spring Networks C&I Gas Meter Interface radio device to the surrounding structure which can
include the meter piping, meter fixtures/supports or some adjacent structure to the meter.
