2.2 Storage
After receiving the vortex insertion flow meter, care should be taken to avoid
unnecessary damage. If the meter is not scheduled to be installed soon after deliv-
ery, the following steps should be observed:
A) After inspection, the meter should be repacked into its original packing.
B) If the meter being stored has been previously installed, care should be
taken to remove all process fluids and corrosives.
C) Select a clean, dry site free of mechanical vibration, shock and chemical
corrosives.
3. INSTALLATION
3.1 Installation
The Aalborg
7 vortex flow meter is designed to operate under a wide variety of con-
ditions. To ensure its longevity of operation, precautions should be taken before
and during its installation.
3.2 Selecting the Installation Site
A) The vortex meter requires a minimum of 20 straight diameters upstream
and 5 straight unobstructed diameters of downstream piping. One
diameter is equal to the internal pipe diameter. This is necessary to ensure
regulated formation of vortices. (See Figure 3 for the piping requirements
chart for various piping recommendations.)
B) Choose a site with minimal mechanical vibrations.
C) Avoid areas of high humidity or corrosive atmosphere where possible.
D) When installing the meter, choose a site which is accessible and allows
ease of wiring and maintenance.
