Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
Panametrics is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back
initiative, directive 2012/19/EU.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the
natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle
most of the materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional
waste administration.

T5 Flare Gas Transducer Installation Guide 1
Chapter 1. Installing Pipe Nozzles
Chapter 1. Installing Pipe Nozzles
1.1 Introduction
Before the T5 transducers can be installed into the pipe, you will need to install pipe nozzles. Nozzles may be installed
as part of a fabricated spoolpiece or by using the hot or cold tap process with a Panametrics Sensing
Nozzle
Installation Kit
.
IMPORTANT: This procedure only applies if you are using a Nozzle Installation Kit. If you are tapping the pipe without
using a Nozzle Installation Kit, refer to the supplied drawings in your shipment. This procedure is written
and illustrated for installations on horizontal pipes. However, the procedure is the same for vertical pipe
installations.
This section describes how to install nozzles in the following configurations:
1. Bias 90o Installation
• Standard transducer spacings of 10” and 9”, with both transducers facing straight at each other, are for
applications with gas velocities up to 100 m/s (328 ft/s). This is the
standard velocity range.
• A shorter transducer spacing of 6.4”, with only the downstream transducer rotated 6° into the flow is for
applications with gas velocities up to 120 m/s (394 ft/s). This is the
extended velocity range.
2. Tilted 45o Installation
• Standard transducer face to face spacings, with both transducer body axes concentric and parallel to
each other are for applications with gas velocities up to 100 m/s (328 ft/s). This is the
standard velocity
range.
• A shorter transducer face to face spacing of approximately 7.85”, with only the downstream transducer
tilted 6° into the flow, is for applications with gas velocities up to 120 m/s (394 ft/s). This is the
extended
velocity
range.
1.2 Bias 90° Installation
This procedure includes the following steps:
• Identifying and checking the nozzle installation kit components
• Selecting and marking the pipe for nozzle locations
• Installing the first welding boss
• Installing the first nozzle
• Installing the second welding boss
• Installing the second nozzle
• Tapping the pipe

Chapter 1. Installing Pipe Nozzles
2 T5 Flare Gas Transducer Installation Guide
1.2.1 Identifying and Checking the Nozzle Installation Kit Components
The Nozzle Installation Kit contains the materials listed below. Use Figure 1 below to help identify each component.
• 2 Nozzles (if purchased)
• 2 Welding bosses
• 1 Jig
• 1 Alignment plate (9”, 10” or 6.4” spacing)
• 1 Spacer flange
• 1 Threaded rod (1” diameter), with washer and nut
IMPORTANT: You will need eight 5/8” studs with two nuts each, or 3/4” studs with two nuts each. The 5/8” studs are
needed for 2”-150#, 2”-300# and 3”-150# flanges. The 3/4” studs are needed for 3”-300# flanges.
After you are familiar with each component, verify that the welding bosses and alignment plate shipped are for the
required transducer spacing and the pipe size described in the following steps.

1.2.1 Identifying and Checking the Nozzle Installation Kit Components (cont.)
1. Check the marking on the end of the welding boss. The pipe O.D. and the bias dimension (i.e., the transducer
spacing
) are engraved on the boss as shown below. Typically,
• For flow velocities up to 100 m/s (328 ft/s), the
10 in. spacing is used on pipes 18 in. (450 mm) in diameter
or larger, while the
9 in. spacing is used on pipes 16 in. (400 mm) in diameter or on larger pipes when
attenuating gases are present.
• For flow velocities up to 120 m/s (394 ft/s), the
6.4 in. spacing is used on pipes 14 in. (356 mm) in diameter
or larger.
Note:
Bias dimension refers to the distance between the center of the nozzle location and the center line of the
pipe.
2. Check the spacing between the holes on the alignment plate, as shown below. The dimensions should
correspond to the bias/spacing dimension on the welding boss.

1.2.2 Selecting and Marking the Pipe for Nozzle Locations
1. For optimum performance, you should select a location that has at least 20 pipe diameters of straight,
undisturbed flow upstream and 10 pipe diameters of straight, undisturbed flow downstream from the point of
measurement. Undisturbed flow means avoiding sources of turbulence such as flanges, elbows and tees;
avoiding swirl; and avoiding disturbed flow profiles. Never install the flowmeter downstream of control valves,
especially butterfly valves. If you cannot find a proper location, please consult with Panametrics
Flow Application
engineering.
2. Use a center finder device to locate the center of the pipe. “EYEBALLING” IS NOT ADEQUATE FOR ACCURATE FLOW
MEASUREMENT!
3. Lightly punch two marks approximately 16 in. apart on the top of the pipe, running along the center line. The two
nozzle locations will be located between these two center punch marks.
CAUTION! Correct nozzle alignment is critical to the successful operation of the flowmeter.
Therefore, all marking, positioning and welding operations must be carried out with the
utmost attention to accuracy. Unless otherwise stated, dimensional positioning of the
nozzles must be held to a tolerance of 1/16 in. (±1.6 mm) relative to each other and with
respect to the pipe centerline. The angular tolerance must be held to 1O. All hole cutting
in process piping must be performed using hot tapping equipment.
WARNING! Be sure to adhere to all applicable safety regulations.

1.2.2 Selecting and Marking the Pipe for Nozzle Locations (cont.)
4. Spray the area between the two punch marks on the top of the pipe with a marking dye product. Using a metal
straight edge, scribe a line between the two punch marks.
5. Along the new scribe line, mark off a length equal to your transducer spacing (10 in., 9 in. or 6.4 in.) and scribe two
lines at least 10 in. in length and perpendicular to the scribe line on different sides of the scribe line.
6. Along each of the perpendicular scribe lines, lightly punch a mark at a distance equal to half of your transducer
spacing (5 in., 4.5 in. or 3.2 in.) from the center line, depending on the bias distance for your transducers. Keep in
mind that the distance along the arc of the pipe (L) from the pipe centerline is slightly greater than the
point-to-point distance through the pipe. These marks pinpoint the centers for the nozzles. Refer to
Table 1 on
page 7
for arc distances for the most commonly used pipe sizes. If your pipe size is not shown in Table 1 , use the
equation in the figure on page 6 to calculate the arc distance.

1.2.2 Selecting and Marking the Pipe for Nozzle Locations (cont.)
IMPORTANT: For a 3.2 in.bias distance, the downstream port must be located on the right side of the long scribe line
when viewed from the downstream end of the pipe (see the figure below). This convention is mandatory
for the 6.4 in. transducer spacing and is optional (not required) for a 10 in. or 9 in. spacing.

7. Scribe a 6 in. long horizontal centerline through each nozzle center location point and parallel to the original
centerline.
1.2.3 Installing the First Welding Boss
1. Each welding boss has four scribe marks indicating the center of the bias.Take one welding boss and line up its
scribe marks with the horizontal and perpendicular scribe marks on the pipe as shown below. Make sure you
position the boss on the pipe so that the contoured end of the boss matches the pipe arc. That is, the shorter side
of the boss should be closer to the original scribed pipe centerline.

2. Clamp the boss in place, using a pipe strap or equivalent, so that it cannot move during tack welding.
3. Check the boss alignment again, and then tack weld the boss in each of the four grooves between the boss
scribe marks. Make sure you keep the boss contour flush with the pipe contour during the entire tack welding
operation. The boss is constructed of carbon steel.
4. Check the alignment again. If the boss is misaligned by 0.02 in. (0.5 mm) or more, remove the boss, grind off the
welds and reinstall the boss.
