Natural Gas Solutions 100G Installation Guide for Direct Mounting on Meters 1
The 100G is Itron's latest gas encoder-receiver-transmitter (ERT
®
) module.
ERT modules are radio-frequency (RF) devices that transmit meter data. The RF meter data
can be received by a reading device that is within transmission distance of the ERT. Itron's
100G ERT module has increased output power over legacy gas ERT modules for increased
RF transmission distance.
This guide covers 100G ERT Module installation on meters from a variety of
manufacturers. Refer to the Meter Compatibility List to ensure you have a meter
compatible with the 100G ERT Module. See the
Meter Compatibility List on page 2.
Transmission Modes
Once installed, the 100G ERT module has three available transmission modes:
Fixed Network Mode In this mode, a 100G ERT module transmits a high-powered
RF message every 60 seconds. Output power in this mode is 250 milliwatts or
+24dBm; expected battery life is 20 years.
Mobile and Handheld Mode In this mode, a 100G ERT module transmits a
medium-powered RF message every 15 seconds. Output power in this mode is 10
milliwatts or +10dBm; expected battery life is 20 years.
(Optional) Hard to Read Mobile and Handheld Mode In this mode, a 100G ERT
module transmits a high-powered RF message every 30 seconds. Output power in this
mode is 250 milliwatts or +24dBm; expected battery life decreases to 15 years in this
mode, however. The Hard to Read Mobile and Handheld Mode should only be used
for 100G ERT modules that are difficult to read under normal conditions, such as
modules installed on roof tops or in sub-basements.
An FCC license is not required to read 100G ERT modules.
