5.2 External silicagel cartridge
The meter can be equipped with an external silicagel
cartridge for installation in severe environment condi-
tions. 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 observed
for repair:
• In case of use with aggressive or dangerous gas, it may
be necessary to send a safety statement with the me-
ter, 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 required.
• 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 Dresser Actaris Gas.
• 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.
