INSTALLATION
Fig 3.2.2: Wafer type - vertical installation
CAUTION:
When installing the vortex meter in a vertical pipe
outdoors we recommend rotating the conduit
connection to face downward reducing the chance of
rain and condensate running down the conduit into
the housing.
3.2.4 Installing the flanged vortex meter
Use bolts, nuts and gaskets in accordance with ANSI B16.5 (user supplied). The ID of the gasket
must be equal to or greater than the ID of the meter bore. Self-centering gaskets are highly
recommended.

3.2.5 Insulating vortex meters with integral converter
When installing a vortex meter with an integral converter in a pipe to measure high temperature
fluids, do not insulate the converter housing or mounting bracket. If it is necessary to insulate the
entire installation, use a remote mounted converter. Custom steam jackets are available if necessary,
please contact your Yokogawa Industrial Automation Representative for more information.
