Veris Verabar V550 Installation Instructions - Manual (Page 2)

4.2.1 Horizontal Piping
For air or gas installations, mount the Verabar in the
upper 160° of the pipe to allow any condensate to drain
into the pipe (Figure 1). For liquid or steam
installations, mount the Verabar in the lower 160° of the
pipe. This allows any entrained air to bleed back into
the pipe for liquid applications and allows condensate
to collect in the instrument piping for steam
applications.
4.2.2 Vertical Piping
The Verabar may be mounted in any location around
the circumference of the pipe for any vertical piping
applications.

4.3 DP Transmitter/Local Indicator
Location
When choosing a Verabar location, consider the DP
transmitter/local indicator location:
• The transmitter must be mounted below the
Verabar for liquid and steam applications.
• The transmitter must be mounted above the
Verabar for air and gas applications.
4.4 Installation Drawings and Bill of
Materials
Additional information is available in the Installation
Drawings and Bill of Materials VB-7061 (also on the
VeraData CD). It contains standard and alternate
transmitter locations and a complete bill of materials
based on the fluid type and sensor orientation on the
pipe.
5.0 INSTALLATION PROCEDURE
5.1 Drill Hole in Pipe
• Completely depressurize and drain pipe prior to
installation of the Verabar.
• Mark the location of the hole through which the
Verabar will be mounted. Use a center punch to
mark the hole to prevent the drill bit from walking
on the pipe.
• Drill the pipe with the proper sized hole per the
following table:
Sensor Size Hole Dia
V550-05 1/2" (13mm)
V550-10 1” (25mm)
V550-15 1-1/2” (38mm)
• Deburr the hole on the inside of the pipe.
5.2 Weld Mounting Flange to Pipe
• With the follower and packing rings already in
place (factory assembled), insert the sensor into
the Spring-Lock body (Figure 3). Loosely bolt
together (hand tight) the sensor, gasket and
mounting flange. Insert the assembly until the tip
of the sensor hits the opposite side of the pipe.
Align the head of the sensor so that the arrow
labeled “flow” on the head is in the direction of
the flow to within 3°. The contour of the weld
coupling should match the contour of the pipe.
Check that the bottom of the weld coupling is in
contact with the pipe wall.
