3.2.6. Mounting fitting assembly into the plastic (metal-plastic) pipeline.
3.2.6.1. Before mounting drain liquid from the pipeline and cut the pipeline
where the flow meter will be installed. Fix the assembly to stationary
supports by clamps where pipeline is cut considering the following
condition: threaded holes M5 on cylindrical surface of the flanges used
to connect wires to the MF case should be in position allowing easy
connection of the wires.
3.2.6.2. Connect pipeline ends to the fitting assembly using fittings of
appropriate typical size which are installed on plastic (metal-plastic)
pipelines.
An adaptor coupling may be used as confusors/diffusors if a
different diameter of the pipe is necessary.
3.2.6.3. After completion of work put the pipeline into operation to check joints
and connections for leakages according to current norms specified for
pipelines of this type.
Wash the system before the simulator is replaced by the flow
meter.
3.2.7. Mounting the flow meter into the metal pipeline.
3.2.7.1. Position the flow meter so that the axis of the measuring block stand is
arranged in vertical plane with maximum deflection of 30. The arrow
on the flow pipe shall point to the flow direction.
NOTES.
1. Before mounting the flow meter into the pipeline remove protection rings
from the flow pipe lining if liquid under control is aggressive towards the
material of protection rings.
2. The flow meter for measuring bidirectional flow may be installed without
regard to the pipeline flow direction.
3.2.7.2. The non-flanged flow meters of Pro-×1×М× versions with protection
rings are automatically centered relative to companion flanges of the
pipeline since outer diameter of external rings matches the diameter of
flange grooves.
When mounting the MF, put new gaskets provided in the delivery
package into the companion flanges.
To move pipeline flanges apart when installing or removing the MF
(simulator), it is recommended to use a special extension tool.
3.2.7.3. When installing flow meters of Pro-×2×М× versions (flanged flow
meters), put bolts into mating flanges of the flow pipe from the side of
the pipeline flanges. Length of the bolts must provide the distance of
minimum 3 mm from a bolt end to the flow meter assembly.
Alignment of the pipeline and flow pipe inner channel is provided
when flow meter flanges are aligned with pipeline companion flanges.
When the simulator is replaced by the flow meter, put additional
gaskets included in the delivery package to provide leak tightness of
joints between flow meter flanges and pipeline mating flanges (if
necessary).
