11.2 LC METER WITH EXTERNAL PULSE OUTPUT DEVICE
The pulse output device replaces the
dynamic seal of a packing gland with a
static seal.
The motion of the meter rotor is
magnetically coupled to the meter when
a POD or other external pulser is used.
The RSCB is not mechanically coupled
to the meter when a POD or other
external pulser is used. The RSCB can
be mounted up to 1000 feet (304.m)
away from the meter. The installer must
provide a suitable bracket to support the
RSCB if it is mounted remotely.
If the RSCB is being mounted directly to
the meter, the RSCB mounting kit is
required.
The POD can only be attached to LC
meters with two piece covers that were
manufactured after 1990.
To install the RSCB mounting kit:
q
Attach the short side of the RSCB
mounting bracket to the RSCB using
the four .250-20 x .750” screws and
lock washers provided.
q
The right angle bend of the bracket
should be lined up with the front of
the RSCB.
q
Attach the bracket and RSCB
assembly to the front meter cover
using the four .250-28 x .750”
screws provided.
q
