Elster American and Itron Commercial Meter Installation
2. Align the ERT module so the screw holes line up with the meter's top screw holes. Carefully lower the
module on the meter with the wriggler notches lining up with the meter's drive dog teeth.
Warning The INLET label on the 100G must line up with the INLET label on the meter case.
3. Verify the bottom of the ERT module and the top of the meter meet. The ERT module housing should rest
on top of the meter without gaps.
Warning Do not press down on the 100G if a gap exists between the ERT module and the meter. A gap
may be caused by misalignment of the ERT module wriggler and meter's drive post. Pushing down on the
ERT module could damage the ERT module wriggler or meter drive post. To eliminate a gap, slowly turn
the ERT module's drive shaft back and forth until the module aligns with the meter's drive teeth.
4. Place the index cover mounting plate on the commercial 100G so the printing "FLOW FRONT AL800
AL1000 AL1400 AL2300 AL5000 TURBINE ROTARY" stamped on the plate is toward the front of the
meter. (A gap between the mounting plate and meter at the screw locations is normal.)
