Veris Verabar V150 Installation Instructions - Manual

Verabar 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 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.
• The Spring-Lock Model V150 is designed for
carbon and stainless steel pipes with a schedule
10 or heavier wall thickness. The V150 should
not be used with PVC, copper, aluminum, cast
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.
