Installation Guide: PETNET System Components
1.0 Overview
This document is intended to guide the user through the initial set-up of a Water Submetering
System. The system is made up of usually one or more PETRC units and up to 1000 PET
modules.
PETRC units are a receiving device that collects information from the PET modules via Radio
Frequencies in the 902 to 928 MHz band and stores this information for later retrieval by various
“head end” software. The device is powered by 110 Volts AC and incorporates a 3dBd gain
antenna.
PET Repeater unit operates similar to the PETRC in that collects information from the PET
modules however , the collected information is forwarded to the PETRC unit via RF. This unit is
equipped with a 5 DbD gain antenna and associated coaxial cable. This antenna and cable
assembly must be used without modification.
The PET module is a transmit only device that transmits its consumption information once each
10 to 15 minutes. The consumption information is gathered continuously from any pulse output
device including Water. The device is for indoor use in a non-condensing environment. The unit
has a battery life of greater than 4 years.
This document is intended to guide professional and trained installer through the initial set-up of
a Water Submetering System. The system is made up of usually one or more PETRC units, PET
Repeaters and up to 1,000 PET modules.
