Meters
This section provides the information to attach the 100G to a Sprague 175RM meter.
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 index cover mounting screws and the index cover from the Sprague 175RM meter. Discard
the index cover and index cover mounting screws.
Note The removed index cover may be used as a temporary refuse container for screws. Properly dispose
the index cover and all unused screws, gaskets, tamper seals, and other leftover materials. Do not leave
materials on customer premises.
2. Loosen the index mounting screws 1/2 to one turn. Slide the index up and off the mounting screws and
remove it from the meter. Set the index aside where it will not be damaged or fill with dirt, rain or snow.
You will mount the index in the module later in this procedure. Remove the index mounting screws from
the meter. Verify the index mounting screws are 1/4-inch long and not corroded. If the screws are the
correct length and not corroded, retain for later use. If the original screws are discarded, use the correct
replacement screws (see Installation Prerequisites on page 14).
