5 Installation in the pipeline
• Installation material, refer to table on page 3.
• Pipe flanges and operating pressure,
refer to table on page 3.
• Pipe flange spacing (fitting dimension)
1) Dimensions including grounding rings
2) No gasket required between measuring tube and pipe flanges, seal provided
by PFA liner on the flanges
s Thickness of gasket D2 between grounding rings and pipe flanges, not
included with flowmeter, to be provided by customer. Use Teflon-type gaskets,
deformable under pressure, to DIN 2690/ANSI B 16.21,
8 - 16 N/mm
2 /1160 - 2320 psi.
• High-temperature pipelines
Where process temperatures exceed 100 °C/212 °F, provide for facilities to
compensate for longitudinal expansion on heat-up of the pipeline.
For short pipelines use resilient gaskets and
for long pipelines install flexible pipe elements (e.g. elbows).
• Position of flanges • Arrangement of centering sleeves
Install flowmeter in line with the pipe 1 washer
axis. Pipe flange faces must be 2 centering sleeve
parallel to each other, 3 stud bolt
max. permissible deviation: 4 hex. nut
