The flowmeter mounted in the pipeline
SHOULD NOT
be rotated
around the pipeline axis.
3.2.7. Mounting the flowmeter with threaded coupling
3.2.7.1. Select
the flowmeter’s pipeline mounting location observing the rules
specified in Table 1. Cut the pipeline drained of liquid following the
instructions given in section 3.2.6.
3.2.7.2. Unscrew grooved nuts and dismount nipple joints which are the parts of
PFC.
3.2.7.3. Make sure that the simulator is installed into the assembly-welded
structure instead of PFC, this is necessary to provide alignment
between two welded units and to avoid damages to the flowmeter
during welding the structure to the pipeline.
Weld conical nozzles to the pipeline butt-to-butt in the same way as
to weld the adaptor pipes for the wafer type flowmeters, so that the
nozzle axis is perpendicular to the grooved nut plane. Welding works
shall be conducted in accordance with the requirements given in section
3.2.6.
CAUTION!
When replacing the simulator by the flowmeter after
welding, it is recommended to use a compensator to ensure that the
threaded couplings are moved apart by the distance of no less than
10 mm. The compensator may be as follows:
-
KRK
manufactured by JSC "ArmaTreid"
-
ARN/HYDRA by Danfoss
-
Compensators from "WILLBRANDT" (authorized distributor is
"KREOLAIN" company), or similar.
The compensator shall be mounted into the pipeline following the
instructions outlined in the corresponding operational (maintenance)
documentation and considering the requirements given in Table 1.
3.2.7.4. Replace the simulator with the flowmeter. The whole structure is
assembled by firm tightening of grooved nuts. When assembling the
structure, it is required to install gaskets made of edible material and
supplied with the flowmeter, between the nozzles and grooved nuts.
3.3. Mounting the secondary converter of the flowmeter
remote version
3.3.1. The place of installation is selected from the condition of convenience of
work with the secondary Converter. Installation dimensions are
specified in the operating manual. When selecting the SC location, the
length of the flowmeter and SC communication cables must be taken
into account.
3.3.2. Do not install SC:
-
In places where the ambient temperature can go beyond 5 to 50°C, and
the humidity can be above 80 %, at a temperature below 35°C
- Near heat sources such as hot pipes. Lighting SC is optional, its display
has its own backlight.
3.3.3. Using screws with a diameter of 5 mm bracket (Fig.C.1) installed on the
wall. Detachable coupling (Fig.C.3) one end is fixed to the rack of the
secondary Converter. The free end of the clutch is put on the bracket
