6. Installation Requirements
Ensure the following when installing the flow meter:
•The flow direction should match the arrow direction on the flow
meter.
•The flange bolts have been fastened to the ma torque rating.
•Mechanical stress (twist and bent) should not e ist when
installation. Mating flanges should keep a ial symmetrical and
parallel, and proper gaskets should be used.
•Gaskets should not be e tended to the flow area, otherwise
whirlpool generated and affecting accuracy of the flow meter.
•Any force and moment from the pipe should not affect the flow
meter.
•The display of the flow meter should face the users.
•Protecting plug of the cable entries are only allowed to be removed
when wiring.
•Remotely installed sensors should be mounted on places that is
almost vibration-free.
•Converter of the flow meter should be free from direct sunshine.
(Shade is required)
Observe the following rules when choosing the installation places:
•No negative pressure in measuring tube.
•Avoid being installed near motor, transformer, and other strong
10 S435

6 Installation
current equipment, to avoid jammer.
•Avoid being installed near strong corrosion gas.
•Avoid being installed in separated place, when measuring mi ed
fluid.
•Avoid being under direct sunlight, ambient temperature should be
-25°C … +65°C.
•Choose places without or with less vibration. If too much vibration,
install fi ed support before and after the pipe.
•Relative humidity is 5% … 90%.
•Avoid direct rain and soaked places.
•Prevent liquid retention.
•The flow meter should be mounted on a vertical pipe to prevent
accumulation of fluid.
•When the flow meter is installed horizontally, raise the pipe section
installed with the flow meter.

6.2 Installation Instructions
6.2. Error between the Inner Diameters of Pipes
•The inner diameter of the pipe should be as close as possible to the
inner diameter of the meter, and there should be no obvious
deviation.
•Ensure that the inner wall of the pipe on both sides of the flow
meter is smooth and free of surfacing.
6.2.2 Straight Pipe Requirements
Description Illustration
1．Flow condition at the entrance
shouldn’t be interfered ≥ 10D
2. Behind the valve ≥ 35D
3. Reducing pipe ≥ 15D
4. One 90° bent pipe ≥ 20D
5. Two 90° bent pipes on one flat
surface ≥ 30D
12 S435

6. Two 90° bent pipes on different
flat surfaces ≥40 DN
1. Downstream Straight Pipe ≥ 5D
2. Measuring point away from
vorte flow meter ≥ (4-6)D
3. Advice: The meter is installed
upstream of the valve
4. Not advice: the meter is
mounted directly behind the valve
5. Ma imum height of insulation
layer
S435 13

6 Installation
Cleaning the pipeline:
1. For newly installed or
repaired pipes, flush out
rust, scale, residue and
sludge from the pipes before
operation.
2. When flushing, water flows
through the bypass line to
avoid damage to the flow
meter.
3. If there is no bypass,
temporarily install a short
pipe to replace the flow
meter.
6.2.3 Wafer Type of Vortex Flow Meter Installation
Wafer Description
Note:
•The inner diameter of the
gasket must be larger
than the inner diameter
of the pipe so that it
does not interfere with
the flow inside the tube.
•When the flow meter is
installed vertically in an
open position, the wiring
port should face
downwards, otherwise it
will leak rain when it
rains.
