Veris V150 Installation Instructions

1.0 SCOPE

These instructions provide procedures for installing the
V150 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 num-

ber, 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.
Damage to the cover tube may prevent the
packing from sealing properly.

3.0 SAFETY PRECAUTIONS

The following tasks should be conducted prior to install­ing 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.

INSTALLATION INSTRUCTIONS

• Check that the pipe is depressurized and drained
prior to installation.

• The Spring-Lock Model V150 is designed for
carbon and stainless steel pipes with a schedule
10 or heavier wall thickness. The V150 should

be used with PVC, copper, aluminum, cast

not
iron or thin-walled pipes or ducts. If there is any
question as to the proper application for a model
V150, consult the factory.

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.

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.

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 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 the 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
V150-05 1/2" (13mm)
V150-10 1” (25mm)
V150-15 1-1/2” (38mm)

• Deburr the hole on the inside of the pipe.
