Removing the Meter Index

Begin the module installation by removing the index cover and index from the meter.

To remove the index from the meter

1. Remove the four index cover screws and the index cover from the Sensus meter. Alternate screw removal

following the numbered pattern as shown in the following photo.

2. Examine the mounting screws. If they are 5/8-inch long and not corroded, keep them to attach the 100G

series gas ERT module assembly. If the screws are not the correct length or if the screws are corroded,

discard them.

Note You may use the removed index cover as a temporary storage container for screws. Properly

dispose all unused screws, old index covers, gaskets, tamper seals, and other leftover materials. Do not

leave materials on the customer premises.
