Veris V550 Installation Instructions

1.0 SCOPE

These instructions provide procedures for installing the V550 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, 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 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.

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

Piping Configuration

Table 1. Straight Run Requirements

Verabar V550 (Flanged Spring-Lock)

INSTALLATION INSTRUCTIONS

• The Flanged Spring-Lock Model V550 is designed for carbon and stainless steel pipes with a schedule 10 or heavier wall thickness. The V550 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 V550, 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 nameplate.

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.

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

V550-05 1/2" (13mm) V550-10 1” (25mm) V550-15 1-1/2” (38mm)

• Deburr the hole on the inside of the pipe.

5.2 Weld Mounting Flange to Pipe

• With the follower and packing rings already in

place (factory assembled), insert the sensor into the Spring-Lock body (Figure 3). Loosely bolt together (hand tight) the sensor, gasket and mounting flange. Insert the assembly until the tip of the sensor hits the opposite side of the pipe. Align the head of the sensor so that the arrow labeled “flow” on the head is in the direction of the flow to within 3°. The contour of the weld coupling should match the contour of the pipe. Check that the bottom of the weld coupling is in contact with the pipe wall.
