Chapter 1. Introduction
Thank you for purchasing a model PanaFlow™ LC from
Panametrics. Please register your product at https://info.
bakerhughes.com/New-Product-Registration-LP.html for
product support such as the latest software/firmware
upgrades, product information and special promotions.
1.1 System description
The PanaFlow™ LC flowmeter is a one, two, or three channel
ultrasonic transit time flowmeter that utilizes clamp-
on transducers on external pipe surfaces to allow for
uninterrupted flow operation during flow measurement. The
PanaFlow™ LC flowmeter has up to 3 independent channels.
These channels are capable of measuring the flow rate of
acoustically conductive single-phase liquid, which may
have limited amount of second phase. With the 3 channels,
the user will have the capability to average them with equal
weights, or with different weights that will better suit the flow
profile. The meter is designed for pipe sizes ranging from ½
in. (15 mm) to 300 in. (7600 mm) with wall thickness up to 4
in. (102 mm) for flow velocities up to 80 ft/s (25 m/s). For a full
list of its capabilities, see Appendix A. This manual will serve
as a guide to install the clamping fixture and transducers
necessary for accurate flow readings, programming
the meter for specific customer needs, error codes and
troubleshooting walk through, and maintenance and service
procedures.
Figure 1: PanaFlow LC
1.2 Theory of operation
The PanaFlow™ LC uses a procedure called Transit-Time
Flow Measurement. In this method, the flowmeter transmits
ultrasonic pulses through a moving liquid. The pulses that
travel in the same direction as the fluid flow (downstream)
travel slightly faster than the pulses that travel against the
fluid flow (upstream). The difference in transit times is then
used to calculate flow velocity.

2.3 Site considerations
Proper installation of the PanaFlow™ LC is important to
achieve optimum performance from the system. The
following installation recommendations provide general
guidelines of how this system should be installed. If the
following recommendations cannot be met, please consult
the factory for a more detailed review of the application to
see what performance may be achievable. Following these
recommendations may not be the solution for all, since
every installation is different.
2.4 Clamping fixtures and
Transducer installations
Installation of clamp-on transducers for transit-time
measurements consists of mounting the clamping fixture
to the pipe and then mounting the transducers into the
clamping fixture. When installing transducers in clamp-on
applications, you can use one of the following methods to
hold the transducer against the pipe wall:
• Strap Clamping Fixture (SCF)
• Universal Clamping Fixture (UCF)
• General Clamping Fixture (GCF, permanent installation)
• Magnetic Clamping Fixture (MCF)
• Small Clamping Fixtures - 6” (150 mm) or 12” (300 mm)
long, with Velcro straps (SPCF)
This manual covers the installation for the Strap Clamping
Fixture (SCF), while the other fixtures can be found in the
Appendix B. Before beginning the transducer installation,
you must determine the number of traverses for your
configuration.
Note: The accuracy and performance of the flowmeter
depends on the location, spacing, and alignment of the
transducers. This manual provides general instructions for
locating and installing most transducer types. However,
the specific spacing of your transducers is unique to your
installation.
2.4.1 Strap clamping fixture
The Strap Clamping Fixture (SCF) (see Figure 5 below) acts
as a spacing device, a transducer holder, and a transducer
aligner. The SCF includes two U-shaped blocks connected
by a slotted bar and four hose straps.
The SCF is strapped around the pipe, and the blocks are
used to hold the transducers in position for accurate
measurements. The blocks must be positioned properly
using the spacing dimension calculated by the flowmeter.
Then, the transducers are mounted into the blocks.
Figure 5: Components of the SCF
4

2.5 Determining the number of
Traverses
The first step in the installation is determining the number
of traverses (see Figure 6 below). The transducers can be
mounted using one of two methods:
• Even number of-traverse method - the transducers
are mounted on the same side of the pipe and the
ultrasonic signal is transmitted from one transducer to
the other by reflection off the opposite pipe wall.
• Odd number of-traverse method - the transducers
are mounted diagonally across from each other. The
ultrasonic signal is transmitted across the pipe directly
from one transducer to the other.
Always try the even number of-traverse method first
because it is easier to configure and yields greater
accuracy. However, if the pipe has poor inside surface
conditions or the fluid is highly attenuating, you may not
be able to obtain a reliable signal. Therefore, you may
have to use the Odd number of-traverse method in such
applications. The spacing of the transducers is calculated
by the system after all the installation parameters have
been programmed into the flowmeter.
Figure 6: Even and odd number of Traverse installation
5

2.6 Precautions
Prior to installation the clamping fixture, it is HIGHLY recommended to keep the following in mind:
1. Position the clamp-on fixture(s) and transducer system so that there are at least 10 pipe diameters of straight,
undisturbed flow upstream and 5 pipe diameters of straight, undisturbed flow downstream from the measurement point
(see Figure 7 below). Undisturbed flow means avoiding sources of turbulence in the fluid such as valves, expansion joints,
elbows and other protruded mechanical components. For location after a set of out of plane double elbows, longer
upstream length is highly recommended.
2. If the clamping fixture is to be placed downstream of an elbow, the orientation of the clamping fixture must be placed in
such a way that the transducer path is perpendicular to the plane of the piping to compensate for swirl.
3. For permanent installations, the clamping fixture should be oriented in a way where the transducer paths are out of the
vertical plane. Pipe fouling can produce erroneous meter readings. If this placement contradicts with the placement
listed in the previous note, then the fixture can be oriented in the 11-5 o’clock or 1-7 o’clock positions. NEVER orient the
transducers in the 12 o’clock or 6 o’clock positions.
4. Once the location has been scoped out, make sure there is enough clearance around the area to install the clamping
fixture and transducers.
Figure 7: Recommended installation location and orientation
6

2.6.1 Even number of Traverse method
Note: The instructions in this section can also be used for a
multiple-traverse method. However, you must use an EVEN
number of traverses. The distance the signal travels from
one side of the pipe wall to the opposite side of the pipe wall
is considered one traverse. For installations with more than
two traverses, contact Panametrics for assistance.
The installation procedure for transducers using the even
number of-traverse method is as follows:
1. Ensure the location of your clamping fixture has been
properly scoped out following the criteria in Section 2.6:
Precautions.
2. Prepare the pipe where you intend to place the
clamping fixture by making sure it is clean and free of
loose material. Sanding, though usually not required,
may be necessary to remove any high spots. However,
be careful to preserve the original curvature of the pipe.
3. Secure one of the blocks to the alignment bar by
tightening one of the nuts on the block so the block will
not be able to slide along the alignment bar’s slot.
4. Obtain the transducer spacing dimension (S) after
programming the XMT1000 transmitter. Using the
alignment bar as a guide, move the second block so
that the distance between the blocks equals the S
dimension. Use the pressure bolts or the edges of the
blocks as reference points, as shown below.
Figure 8: SCF setup, spacing
5. Position the clamping fixture on top of the pipe and
wrap the clamping fixture blocks with the hose clamps.
Tighten the clamps until the blocks are snug but ensure
that they can still be rotated around the pipe.
6. Rotate the blocks so that they are away from the vertical
plane and in an orientation that satisfies the criteria
listed in Section 2.6: Precautions.
7. Fully tighten the hose clamps so no movement on the
fixture will occur.
Figure 9 below shows a completed even-traverse
installation without the transducers. Proceed to the section
on mounting the transducers later in this chapter.
Figure 9: Finished SCF installation without Transducers
2.6.2 Odd number of Traverse method
Note: The instructions in this section can also be used for a
multiple-traverse method. However, you must use an ODD
number of traverses. The distance the signal travels from
one side of the pipe wall to the opposite side of the pipe wall
is considered one traverse. For installations with more than
one traverse, contact Panametrics for assistance.
The procedure for mounting the SCF for the odd number of-
traverse method includes marking the pipe for the required
transducer spacing, fastening the fixture to the pipe, and
then mounting the transducers into the fixture.
To install the SCF odd traverse, complete the following steps:
1. Ensure the location of your clamping fixture has been
properly scoped out following the criteria in Section 2.6:
Precautions.
Note: For simplicity, all figures will show the clamping fixture
oriented on the horizontal plane (3 o’clock and 9 o’clock
positions). Exact orientation will depend on the piping
upstream and downstream of the fixture determined in
Section 2.6: Precautions.
2. Prepare the pipe where you intend to place the SCF
by making sure it is clean and free of loose material.
Sanding, though usually not required, may be necessary
to remove any high spots. However, be careful to
preserve the original curvature of the pipe.
7

3. Use a level to find the top of the pipe and then draw a
line parallel to the centerline of the pipe.

4. Using a level and center punch, make two marks on the
line drawn in step 3. These marks must be separated by
the transducer spacing distance S, as calculated by the
flowmeter.

5. From one of the marks on the top of the pipe, measure
around the pipe a distance equal to 1/4 of the pipe
circumference, or a distance that will satisfy the
orientation found in Step 1. Use the center punch to
make a mark at this point.

6. From the other mark on the top of the pipe, measure
around the pipe in the opposite direction a distance
equal to 1/4 of the pipe circumference, or the same
distance used in Step 5. Use the center punch to make a
mark at this point.

7. Center one of the blocks over one of the center punch
marks on the side of the pipe. Align the block so that the
pressure bolt is directly over the punch mark. Secure the
block by wrapping the two steel straps around both the
block and the pipe and tightening the straps.

8. Repeat Step 7 to install the other block on the pipe.
IMPORTANT:
Make sure both straps are perpendicular to the bottom of
the block. If the straps are slanted, the slack will cause the
block to move. Also, the transducer spacing dimension
may change after the transducers are mounted.
