Veris Verabar V250 Installation Instructions - Manual (Page 2)

Figure 2. Verabar Model V250
4.2.2 Vertical Piping
The Verabar may be mounted in any location around the
circumference of the pipe for 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.
4.5 Piping Support
For sensors that extend more than 36” (915mm) beyond
the pipe wall or for sensors mounted in thin-walled pipes,
external support of the Verabar is recommended. This
will reduce stresses on the pipe wall.
5.0 INSTALLATION PROCEDURE
5.1 Assemble the Verabar
Your Verabar is shipped loosely assembled and is not
properly tightened for proper pressure retention. Follow
all assembly steps to ensure a safe installation.
5.2 Install Instrument Valves or Manifold
5.2.1 Valves
If the Verabar does not have a valve head, install
instrument valves using proper thread sealant (Figure 2).
Be sure instrument shut-off valves are installed and shut
prior to repressurizing the pipe.
5.2.2. Manifold
If the Verabar has a direct or integral manifold, be sure
the high and low pressure block valves are shut off prior
to repressurizing the pipe.
