T

g
impellers
separate
the flowing gas
into small, finite volumes and are counted using a mechanical
index. The
RABO
meter
has no wearing parts
because
precision
clearances between
the impellers and meter body
are maintained by timing
gears,
which are
designed
to
enhance
long term accuracy. Combining
adequate
filtration
and periodic
maintenance,
a
RABO
meter will remain accurate
over many
years.
As the
left
impeller
rotates
toward the
vertical
position, gas enters the
cavity
created
between the
impeller and the
housing.
When the
left
impeller
reaches
the vertical
position, a
finite
volume of gas is
captured in
the
left
cavity.
As the impellers continue
to turn, the volume of gas
in the
left cavity
is
discharged.
Simultaneously, gas is
entering the space
between
the right impeller
and
housing.
After
further rotation,
the
right impeller
becomes
vertical
and a
finite
volume of gas is
captured in
the
right
cavity.

5. Installation
Elster
RABO
meters can be installed in horizontal or vertical
(top inlet) piping configurations. Vertical (top inlet) piping is
preferred
because
it
enables
the meter to pass
contaminants
more freely through the meter.
All
piping should
be properly
supported
and aligned to eliminate any strain on
the meter, which may
cau
se
the impellers to bind.
Recommended
piping practices include a
filter
or strainer on
the
inlet of the meter and non-lubricated isolation valves. A
bypass
line will facilitate
maintenance
and removal of the
meter
and

d
e

n
t
e

u
pp
l
y
.
The meter should not be installed lower than the outlet pipe
run.
If it
is
necessary
to install the meter lower than the outlet
pipe run, installation of a drip leg in the outlet piping to capture
condensate
is
recommended.
The meter should never be
located at the lowest point in the system.
A restricting
orifice
can also be installed at least 4 pipe
diameters downstream
of the outlet of the meter to prevent
the meter from flowing excess capacity. Warranty does not
cover failures due to excess
flow
conditions.

The odometer index can be used to calculate the
instantaneous flow rate by using the right-most digit (test
dial). Each number on this dial represents one (1) cubic
foot, and one complete revolution of this dial represents
ten (10) cubic feet. You will need a stop watch or a watch
with a sweep second hand to calculate flow rate.

Figure 26. Support bracket attachment
(2) Using a 5mm Allen wrench, loosely install two M6
socket head cap screws through the support bracket
into the meter case cover [Figure 26]. The screws
will be tightened after alignment of all parts.
xiii) Install the adaptor plate assembly
(1) Lubricate the adaptor plate assembly O-ring with silicone
O-ring grease, light machine oil or petroleum jelly.
(2) Carefully align the slot of the output shaft to the flat of the
ID index output [Figure 27].
(3) Fully insert the adaptor plate assembly post into the
index cover output hole.
(4) Orient the adaptor plate to the desired direction (4
positions are possible: Facing away from the meter,
facing the meter, facing the meter inlet, or facing the
meter outlet).
xiv) Using a 5mm Allen wrench, install two M6 socket head
cap screws through the adaptor plate into the support
bracket assembled in a previous step [Figure 28].
Tighten to 45-50 in-lbs.
xv) Using a 3mm Allen wrench, install two set screws
through the index cover neck to secure the adaptor plate
assembly [Figure 29]. Tighten snuggly.
xvi) Tighten the two M6 socket head cap screws installed
earlier (to affix the support bracket to the meter case
cover) to 45-50 in-lbs.
xvii) Check for binds: Using compressed air blown into the
meter inlet port, confirm the index and the instrument
drive rotate freely
xviii) Install security seals as required
(1) Security wires are included to secure the index cover
mounting screws and the support bracket lower mounting
screws.
(a) To install, feed the security wire through the holes in
the drilled head screws, thread the free end of the
wire through the hole in the center of the seal, pull
tight, and snap the seal together.
(2) Red Security seals (plugs) are included to seal the support
bracket upper mounting screws.
(a) To install, press the seals in the adaptor plate holes
over the screws until they are fully seated.
b) Changing the meter from horizontal to vertical flow and
vice versa
i) Remove instrument from instrument drive if applicable
(refer to instrument manual for detailed information).
ii) Using a 3mm Allen wrench, remove the two set
screws from the index head.
iii) Using a 5mm Allen wrench, remove the two M6 socket
head cap screws from the adaptor plate.
iv) Pull the adaptor plate assembly off the index head with
a smooth rectangular movement.
v) Using a 5mm Allen wrench, remove the two M6 socket
head
cap screws that affix the support bracket to the
case cover.
vi) Rotate the complete index assembly into the desired
position depending on the meter orientation.
vii) Re-Assemble the instrument drive using the steps
described in a) xii) to xviii).
(1) for 3.5M and 5.5M meters use the support bracket
that you removed before.
(2) for 9M and 14M meters use the additional support
bracket that was supplied with the instrument drive kit
or with your meter.
15. Auxiliary Equipment Mounting
All RABO meters are equipped with threaded holes for mounting
compact, lightweight auxiliary equipment [Figures 30 and 31].
All holes are M6 x 1 by 10mm deep. Heavier equipment should
be pipe or wall mounted adjacent to the meter. Elster provides
customized brackets for commonly used equipment [Figure 32].
Please contact your local Elster representative for details.

16. Direct mount TCI or EC350
The RABO meter can be shipped by the factory with either a Honeywell Mercury Instruments Temperature Compensation
Index (TCI) or an Electronic Volume Corrector (EC350) directly mounted to it, with or without an Automated Meter Reading
(AMR) device attached to it. The TCI is an advanced, yet simple to use, electronic temperature compensating index available
for natural gas rotary meters. The TCI is an ideal replacement for mechanical TC indexes.
For higher volume application and greater accuracy, the RABO meter can be fitted with the EC350. The EC350 is Honeywell’s
latest Gas Volume Corrector platform. It features new high accuracy/stability digital pressure transducer, Cellular 4G/LTE
communication, advanced audit trail capability and lowers ownership and operating costs
Detailed assembly instructions can be found in the manual delivered with the corrector or temperature compensation index.
