Installing the 100G ERT Module
Natural Gas Solutions 100G Installation Guide for Direct Mounting on Meters 59
To attach the 100G ERT Module to the meter
1. Get two new ERT module mounting screws (part number SCR-0014-004).
2. Carefully place the ERT module assembly on the meter. Make sure the meter drive
dog aligns with the white wriggler drive slot.
3. Make sure there is no gap between the 100G ERT Module and the meter.
If there is a gap, the end of the meter drive dog is probably riding on the face of the
ERT module wriggler drive post instead of in its drive slot. To eliminate the gap:
Remove the ERT module. Repeat step 2 to align the ERT module drive dog.
WARNING! If the drive slot of the 100G ERT Module wriggler is not properly
aligned with the meter wriggler drive dog, there may be a gap between the gasket and
the meter. To correct this, remove the assembly and repeat the alignment procedure.
Failure to place the drive post into the drive slot can cause binding and lead to poor
registration or meter failure.
4. Turn each screw 1/4 to 1/2 turn after it contacts the cover.
