5 1 Installation requirements
Ensure the following when installing the product:
•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

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 … +65 ;℃
•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.

5 2 Installation instructions
5 2 1 Error between the inner diameters of the 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.
5 2 2 Straight pipe requirements

S435 13

n 5 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.
5 2 3 Wafer type vortex flow meter installation diagram
Wafer Description
Note:
1. 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.
2. 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.
