Chapter 2 American Meter Installation
To Attach the ERT to the Meter
1. 5B 225 Meters Only If you are installing the ERT on a 5B 225 aluminum meter, cut
1/16-inch off each post of the ERT wriggler to prevent it from rubbing on the face of
the nut that holds the wriggler in place. If you are not installing on a 5B 225 meter,
continue to step 2 below.
2. Set the wriggler to the desired position for mounting the ERT module assembly to the
meter.
• For One-Foot Meters: Align the ERT module assembly wriggler with the
meter drive post (as shown below). Make sure the ERT wriggler is
perpendicular to the meter drive post.
