Verabar V110
INSTALLATION INSTRUCTIONS
1.0 SCOPE
These instructions provide procedures for installing the
V110 Verabar flow sensor. Procedures are given for all
industrial flow measurement applications including liquid,
steam and gas service for both horizontal and vertical
piping configurations.
2.0 RECEIVING INSPECTION
The following tasks should be performed as part of the
receiving inspection procedure:
Check items received against the packing list.
Check sensor nameplate for proper model number,
serial number and customer number.
Verify that the actual pipe diameter matches the ID
stated on the sensor nameplate.
Check the bullet shaped sensor tube for any signs
of damage. Damage to the sensor tube may result
in erroneous flow readings.
Check the round cover tube for any damage,
especially axial gouges or scratches. Damage to
the cover tube may prevent the ferrule from sealing
properly.
3.0 SAFETY PRECAUTIONS
The following tasks should be conducted prior to install-
ing the Verabar flow sensor:
Check maximum operating conditions on the flow
sensor nameplate and verify that they exceed the
maximum conditions of the installation. If any
pressure, temperature or flow limits will be
exceeded, consult the factory before proceeding.
Check that the pipe is depressurized and drained
prior to installation.
Check that all pressure containing components are
properly installed and tightened prior to
pressurizing the system.
4.0 INSTALLATION PREPARATIONS
4.1 Location
For the most accurate flow measurement, a minimum
straight run of pipe is required. Table 1 shows the
minimum straight run requirements. If longer straight
runs are available, position the Verabar such that the
ratio of upstream straight run to downstream straight run
is approximately 4 to 1. If straight run lengths are less
than the values stated in Table 1, consult the factory for
additional accuracy and location information. For
additional piping configurations, see Drawing SUB-4521.
Position straightening vanes such that the end closest to
the Verabar is half way between the Verabar and the
closest upstream configuration. For elbow installations,
mount the Verabar in the same plane as the closest
upstream elbow.
4.2 Orientation
Verify the proper sensor orientation by checking for an
“-H” (horizontal piping) or a “-V” (vertical piping) in the
model number on the Verabar name plate.
