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 meter
can be verified by a visual control of the totaliser (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 obser-
ved for repair:
• In 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.
• Some gas may still be present inside the meter and
the pipe; therefore sufficient ventilation is requi-
red.
• Repairs and maintenance must be done by trained
or qualified personal. Afterwards a tightness test
with 1.1 x PS (Pmax) must be performed.
• When changing pressure-bearing parts, ensure
that spare parts that comply with the PED are used.
• The 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 catalogue".
• If 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.
• Use solvent and alcohol free cleaning product to
clean the meter.
