ELSTER RABO Rotary Gas Meter

4. Receiving, Handling and Storage

Elster RABO meters should be handled with care to protect
the product from damage. If the package shows evidence
of damage through mishandling in transit, you should notify
the shipper immediately, file a claim with the carrier and notify
your Elster supplier.
Damage to internal components
visible external damage. All new
inspected and checked for free rotation of the impellers
by lightly blowing into the inlet of the meter. This slight
air pressure should cause the impellers to rotate freely and
come to a stop slowly.
NOTICE
DO NOT attempt to make any repairs. Tampering with the
meter may void warranty coverage.
If a meter shows signs of external damage, or if the
impellers do not rotate freely, contact your local Elster sales
representative for return instructions.
Elster RABO meters are supplied with oil in a separate
container. A material safety data sheet (MSDS) is available
upon request.DO NOT put oil in the meter until it is installed
and leveled in the gas piping system. Meters containing oil
that are transported or not installed level may lead to
contamination of the measurement chamber, and will impact
accuracy.
Store Elster RABO meters in their original shipping container
in a dry location until installation. If prolonged storage is
experienced, RABO meters should be tested for accuracy
before installation.

5. Installation

Elster RABO meters can be installed in horizontal or vertical
(top inlet) piping configurations. Vertical (top inlet) piping is
preferred because it
contaminants more freely through the meter. All piping should
be properly supported and aligned to eliminate any strain on
the meter, which may cause 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 provide uninterrupted gas supply.
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.
