module. Output spacing represents an off-time between pulses.
Mounting the 100G Series Gas ERT Module
Select an appropriate mounting location on adjacent piping close to the meter. Using the pipe bracket,
mounting plate and band clamps from the Pipe Installation Kit (Itron part number CFG-0005-003), secure the
100G series remote gas module. Use the cable ties from the kit to secure any excess wire to the piping (see
Mounting the Remote ERT Module a Pipe on page 10).
