1 Important information for installation: PLEASE NOTE !
• 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 20-50 Hz with the IFC 010 K / IFC 020 K and 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.

• Use only solventless detergents to clean the signal converter housing (polycarbonate).
• Temperatures
Refer to Section 11 ”Limits” for operating pressure and vacuum load based on flange
standards and type of tube liner.
