Installation in the pipeline
•
Installation material not included, to be provided by customer
(stud bolts, nuts, gaskets, etc.).
•
Pipe flanges and operating pressure: refer to “limits“ tables in Section 5.6
•
Distance between pipe flanges:
see fitting dimension a in Section 5.5 “Dimensions and weights“
•
High-temperature service
Where process temperatures exceed 100°C/212°F, provide 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).
•
Flange position:
Install flowmeter in line with pipe axis.
Pipe flange faces must be parallel to each other.
•
Gaskets
No additional gaskets required for primary heads fitted with tube liners of Teflon
®
- PFA or
Teflon
®
- PTFE. Refer to Sect. 1.6 for torques.
•
Grounding rings / protection rings (option)
On plastic pipelines and internally coated metal pipelines, grounding rings are required to
form the conductive connection with the process liquid. Refer to Sect. 7 “Grounding“ for
electrical connection.
Please note:
The cylindrical neck must be inside the measuring tube
(to protect the liner, particularly at the inlet edge).
