4 Installation and operating instruction ALTOFLUX M900 and 3080 K
1 Important information for installation: PLEASE NOTE !
• Temperatures
Refer to Section 11 “Limits” for operating pressure and vacuum load based on flange
standards and type of tube liner.
Ambient temperature Process temperature
Compact system 3080 K -25 to +60 °C (-13 to +140 °F) -25 to ≤ +60 °C (-13 to ≤ +140 °F)
-25 to +40 °C (-13 to +104 °F) -25 to > +60 °C (-13 to ≤ +194 °F)
ALTOFLUX M900 -25 to +60 °C (-13 to +140 °F) -25 to > +60 °C (-13 to > +140 °F)
In storage -20 to +60 °C (- 4 to +140 °F), (Neoprene liner)
-25 bis +60 °C (all other liners)
avoid moisture and sunlight.
Transport - 5 to +50 °C (- 4 to +140 °F), (Neoprene liner)
-25 bis +60 °C (all other liners)
avoid moisture and sunlight.
• Location and position as required,
but electrode axis
X – • – • – • – X
must be approximately horizontal in a
horizontal pipe run.
Y terminal box or converter housing
• Measuring tube must be completetly filled at all times.
• Direction of flow is arbitrary. Arrow on flowmeter can normally be ignored. For exceptions,
refer to Section “Factory settings” in the installation and operating instructions for the signal
converter.
• Stud bolts and nuts: to fit, make sure there is sufficient room next to the pipe flanges.
• Vibration: support the pipeline on both sides of the compact flowmeter. Level of vibration in
conformity with IEC 068-2-34: below 2.2g for compact flowmeters in the frequency range of
20-150 Hz with the IFC 090 K.
• Do not expose to direct sunlight, fit a sunshade if necessary, not included with flowmeter,
to be provided by customer.
• Large meter sizes (≥ DN 200 / ≥ 8”), use adapter pipes to allow axial shifting of the
counterflanges and to facilitate installation.
• Strong electromagnetic fields, avoid in vicinity of flowmeter
• Straight inlet run minimum of 5 × DN and outlet run minimum of 2 × DN,
(DN = meter size), measured from the electrode axis.
