Figure 19. Horizontal installation
14. Auxiliary Equipment Mounting
All RABO meters are equipped with threaded holes for mounting
compact, lightweight auxiliary equipment [Figures 19 and 20].
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 21].
Please contact your local Elster representative for details.

13. Thermowell
All RABO meters come equipped with two (2) ¼" NPT auxiliary
ports on the meter body [Figure 18], which can be used for sensing
pressure and temperature of the flowing gas. A thermowell is
required when using a temperature sensing device. Thermowells
are available as accessories to the meter.
a) Installing a Thermowell
1. If meter is not installed in the gas piping, go to Step 5.
2. Slowly open bypass valve.
3. Slowly close the meter’s outlet valve, then the inlet valve.
4. Slowly, completely depressurize the meter piping.
5. Remove one of the plugs in the meter body by using a
¼" hex key.
6. Apply Teflon tape or pipe dope to the male threads of the
thermowell. Wipe excess pipe dope off the thermowell
probe and leading threads to ensure no pipe dope
enters the metering chamber.
7. Screw the thermowell into the meter and tighten to
18 ft-lbs.
8. Re-pressurize the meter as instructed in Start-up/
Commissioning (see section 6).

(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) 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.
