Meter installation
Before installation, keep the equipment in its original packing, sheltered from bad weather and
possible impacts.
The meter should be installed in the measurement line with proper alignment of upstream and
downstream flanges so that stress on the equipment body is avoided.
Figure 6. Proper pipe alignment for meter installation
The equipment must be installed by using the proper tools (wrenches):
•
Never use a hammer
•
Use impact wrenches with caution; pay attention to torque recommendations
•
Specific tools can be used, when necessary, for the spacing between flanges.
If used, leave lift mechanisms in place until all bolts have been tightened.
Gaskets
Check to ensure that the proper gaskets are installed according to flange type: ASME B16.20 and
ASME B16.21 or NF EN 1514 and NF EN 12560 standards.
NOTE: Spiral wound gaskets are forbidden for flanges rated below class 300 or PN 63.
Never reuse gaskets.

UL & cUL Installation
Magnetic sensor assemblies are UL and cUL certified for use in Class I, Div 1, Groups C and D
hazardous locations, with several combinations of coils and preamps.
Ambient temperature must remain within -50 and 80°C. An optional thermal extension can be
used to handle liquids heated up to 150°C.
