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
