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

.
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.
