3.3 Start up
3.3.1 Installation with only an upstream valve
Open the valve very slowly until the meter starts to ope-
rate. Increase slowly the pressure in the downstream
pipe (max. 0,3 bar/second). When the downstream pres-
sure is stabilised, open the valve completely.
3.3.2 Installation with upstream and down-
stream valves
Close the downstream valve. Open slowly the upstream
valve (max. 0,3 bar/second). When the pressure is stabi-
lised in the meter, open gently the downstream valve to
maintain the pressure in the meter and to avoid over-
flow.
3.3.3 Installation with a by-pass
Close all valves. Slowly open the by-pass and wait until
the downstream pressure is stabilised. Then proceed as
§3.3.2. Close the bypass.
After start up, please check the pressure tightness of the
installation. Check also that the maximum flow rate of
the meter is not exceeded.
4 Transmitters
The Fluxi 2000/TZ is equipped as standard with 2 Low
Frequency (LF), Reed switches and an anti-tampering
switch (AT).
Transmitters installed as option:
• Inductive medium (MF) or high frequencies (HF) trans-
mitters.
• A Cyble sensor can be installed onto the totaliser at
any time, see Annex 3. The Cyble sensor is a bounce-
free transmitter. It allows also the counting of eventual
back flows.
• A mechanical drive designed according to EN 12661
can be fitted onto the totaliser, it may be used to drive
removable accessories. Maximum torque applicable
on the output shaft as indicated onto the device must
be respected. When not used, the protection cap must
remain in place.
Remarks about using the meter in potentially hazardous
areas (ATEX):
• Pulse transmitters must be connected to intrinsic safe
circuits, according to EN 60079-11.
• Clean the meter head only with a damp cloth.
• All exposed aluminium parts must be suitably protec-
ted (using paint, varnish, etc) if a film of rust is possible
from dust in the environment.
• The meter must be taken in account in the lightning
risk evaluation of the complete installation.
• Tools used for installing, removing or repairing the
6
meter on site must be appropriate for use in the ha-
zardous area bearing in mind that the hazardous area
classification during meter replacement may differ
from that during normal meter operations.
• The meter shall not be exposed to flame, ionising radi-
ation, ultrasound or strong electromagnetic field.
• Ambient temperature conditions must be con sidered,
including possible additional heating effects due to
other devices in immediate vici nity.
Pulse values and maximum frequencies are given in An-
nex 5.
Electrical characteristics and wiring of the socket are gi-
ven in Annex 4. The wiring of the transmitters is written
on the nameplate of the meter.
Protection of sockets: When a transmitter is not used, the
plastic cap must remain screwed to protect the electric
contacts of the socket.
5 Maintenance
When properly installed and put into service, the Fluxi
2000/TZ needs no particular attention and will provide
you with many years of satisfactory service.
5.1 Lubrication
Meters equipped with an oil pump have to be periodi-
cally lubricated.
Oil is delivered with the meter. Specific oil has to be
used, for example:
  – Aeroshell fluid 12 MIL6085A
  – Isoflex PDP38 (Klüber)
  – Anderol 401D (Mobil Oil)
  – Univis P38 (Shell)
  – Quantity of oil to be filled:
a) On commissioning to fill the volume between the
pump and the bearings
