5.2. External silicagel cartridge

The meter can be equipped with an external silica-
gel cartridge for installation in severe environment
conditions. To replace the cartridge, unscrew the
old cartridge, remove the protective plug of the
new cartridge and screw it into the totaliser.

5.3. Inspection and repair

The proper installation and functioning of the me-
ter can be verified by a visual control of the tota-
liser (to check that the meter runs properly). It is
possible to check the good functioning of the Fluxi
2000/TZ by applying a spin test. This test will give
information about eventual friction in the turbine
ball bearings.

The test has to be conducted as follow:
– Accelerate the turbine wheel around 30 to
50% of Qmax then to measure the time until
the turbine wheel stops.
– Measure the spin time (ST) until the turbine
wheel stops.
See Annex 6 for typical values of spin time.
The following recommendations have to be ob-
served for repair:
• I n case of use with aggressive or dangerous gas,
it may be necessary to send a safety statement
with the meter, detailing the type of Gas that
has been measured.
• S ome gas may still be present inside the meter
and the pipe; therefore sufficient ventilation is
required.
• R epairs and maintenance must be done by trai-
ned or qualified personal. Afterwards a tight-
ness test with 1.1 x PS (Pmax) must be perfor-
med.
• W hen changing pressure-bearing parts, ensure
that spare parts that comply with the PED are
used.
• T he right spare parts are traced by providing
the serial number of the meter to Itron and/or
by using the Itron CD ROM "Spare parts cata-
logue".
• I f used with wet gas, internal and external effect
of corrosion has to be checked regularly and in
case of severe corrosion, the meter must be
replaced.
• U se solvent and alcohol free cleaning product
to clean the meter.
