Veris Verabar V100 - 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 (Figure 1).

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
V100-05 1/2" (13mm)
V100-10 1” (25mm)
•
Deburr the hole on the inside of the pipe.
