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 max torque rating.
• Mechanical stress (twist and bent) should not exist when
installation. Mating flanges should keep axial symmetrical and
parallel, and proper gaskets should be used.
• Gaskets should not be extended 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

5 Installation
current equipment, to avoid jammer;
• Avoid being installed near strong corrosion gas;
• Avoid being installed in separated place, when measuring mixed
fluid;
• Avoid being under direct sunlight, ambient temperature should be
-25 … +65 ;℃
• Choose places without or with less vibration. If too much vibration,
install fixed 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.
