Retrofit Installations
Follow these procedures to remove the existing hardware:
1. Relieve the pressure from the process piping to the
meter.
2. Drain the meter by opening the meter’s drain plugs.
NOTE 1:
Meters with only two packing gland
mounting screws are limited to four orientations.
NOTE 2:
When using a cable gland to seal the wire
entrance, any of the eight orientations can be used.
However, when using conduit, the hub should face
down so moisture that may accumulate in the
conduit will drain away from the POD electronics.
3. Remove the mechanical counter, adjuster, and
adjuster drive shaft from the front of the meter.
4. Some meters have a counter adapter bracket which
is bolted on. If this is the case, remove the counter
bracket by removing the bolts that hold it in place. If
the counter adapter bracket is integral to the meter,
it cannot be removed. In this case, one of four POD
Pulser Extensions will be required.
1. Remove the packing gland mounting screws. Pull the packing gland out of the meter. If
the O-Ring does not come out with the packing gland, be sure to remove it from the
packing gland well before installing the POD.
