Mounting the meter tube
The flowmeter sensor can be installed at any location in a pipeline subject to compliance with
the installation conditions.
1.
Position the flowmeter sensor coplanar and centered between the pipes.
2.
Install gaskets between the surfaces of the flowmeter sensor and the counter flange.
Important
The flowmeter sensor gaskets and the flowmeter sensor must be centered. This will ensure
accurate measurement results. Do not allow the gaskets to extend into the pipeline.
Otherwise the flow profile will be distorted.
3.
Use the appropriate screws for the holes.
4.
Slightly grease the threaded nuts.
5.
Tighten the nuts in a crosswise manner as shown in the figure. Observe the selected
tightening torque!
Important
Torques for screws depend on temperature, pressure, screw and gasket materials. The
relevant applicable regulations must be taken into consideration.
First tighten the nuts to approx. 50 % of the maximum torque, then to 80 %, and finally a
third time to the maximum torque. Do not exceed the maximum selected torque.

Important
Tighten flange screws and nuts to prevent them coming loose. This is recommended in the
case of pipeline vibration. Supports/damping devices should always be installed to prevent
pipeline vibration.
