5 Installation in the pipeline
• Installation material not included, to be provided by customer (stud bolts,
nuts, gaskets, etc.)
• Pipe connections, operating temperature and pressure:
refer to tables on “Limits” in Section 6.
• Fitting dimension
see Sect. 12 “Dimensions and weights”;
• 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 connections
Install flowmeter in line with the pipe axis. Pipe
connections must be parallel to each other, max.
permissible deviation:

• Torques
For flanged instruments
to DIN 11864-2a
Tighten down stud bolts and nuts
with max. torque:
32 Nm ~ 3.2 kpm ~ 23.5 ft x lbf
