Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
Baker Hughes 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.

Chapter 1. Introduction
Chapter 1. Introduction
1.1 Overview
The T17 ultrasonic flow transducer is used exclusively with the Panametrics line of ultrasonic flowmeters. These
transducers measure the flow rate of sonically-conductive gases through pipes having diameters between 12 in.
(305 mm) and
120 in. (3000 mm). This manual provides details on the following topics:
• Transducer construction
• Nozzle installation
• Transducer installation
• Maintenance
• Specifications
Note: For installation on pipes ranging from 4 to 12 in. (100 to 300 mm), or for using the BIAS 90° configuration,
please see the Panametrics 916-117 Installation Guide.
1.2 Transducer Construction
Each T17 transducer assembly (see Figure 1 below) consists of the following components:
• A fully sealed, welded, all metal body made from grade 2 titanium as standard
• A transducer head that consists of piezoelectric elements wired to the BNC connector
• A BNC style connector for use in connecting the transducer to the flowmeter
The T17 transducer is available in standard lengths of 33 in. (840 mm) to 60 in. (1500 mm) and with either a 180o or
174o angled head.

1.3 Certification and Safety Statements
To maintain DEKRA certification, the transducer is provided with a ATEX and IECEx certified compression fitting and/or
adapter of either thread M25 X 1.5 (material: brass) or ¾” NPT (material: 316 SS), both with tube size of 0.50” O.D. For
example: Tyco part number 496SSGL34Ex ATEX certified under BASEEFA 08ATEX0327X and IECEx BAS08.0107X, Peppers
adapter part number ARB/NP/075NPT/M20 ATEX certified under SIRA09ATEX1322X or SIRA09ATEX4323X and IECEx
SIR09.0121X and reducer Capri part number 740724 ATEX certified under LCIO8ATEX6085X and IECEx LC018.0035X or
equivalent parts. ATEX/IECEx certified enclosure, Type Ex d IIC. For example: International Metal Engineering PTE
Limited (IME) Type 8080, 8075, 8066 or 7080 certified under SIRA 07ATEX1331U and IECEx SIR 07.0111U or equivalent that
complies with EN 60079-0:2012/IEC 60079-0:2011 and EN 60079-1:2007/IEC 60079-1:2007. For example: Cortem SL-26.1N
certified under CESI 03ATEX032U or equivalent. A certified metric-to-NPT adapter (material: brass) may be used in
addition to the compression fitting in applicable configurations. Both fitting and adapter to comply with EN
60079-0:2012/ IEC 60079-0:2011 and EN 60079-1:2007/ IEC 60079-1:2007 for Ex d IIC. For electrical connection, the
transducer must be mounted into a certified metal enclosure with type of protection flameproof enclosure “D”,
complying with EN 60079-1:2007 and IEC 60079-1:2007 Ex d IIC. Measures must be taken to ensure a good electrical
contact and to prevent the threads from self-loosening. The compression fitting is suitable for temperatures –60°C
to 250°C.

Chapter 2. Installing Pipe Nozzles
Chapter 2. Installing Pipe Nozzles
2.1 Introduction
Before the T17 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 process with a Panametrics 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 different available configurations:
• Standard flow range operation of 0.1 to 328 f/s (0.03 to 100 m/s):
This configuration uses two 180° head T17 transducers.
• Extended range operation of 0.1 to 394 f/s (0.03 to 120 m/s):
This configuration uses one 180° head T17 transducer and one 174° head T17 transducer.
Either of these arrangements may be used on one of two path configurations:
• A diametrical path configuration (the signal path forms a line through the pipe diameter (see Figure 2 below).
• A non-diametrical path configuration (the signal path forms a line offset from the diameter (see Figure 3
below.
Figure 2: Diametrical Path Configuration
Figure 3: Non-Diametrical Path Configuration
2.2 Diametrical Path Nozzle Installation
This procedure includes the following instructions:
• Identifying and checking the nozzle installation kit components
Chapter 2. Installing Pipe Nozzles

• Selecting and marking the first nozzle location
• Determining and marking the second nozzle location
• Installing the first welding boss
• Installing the first nozzle
• Installing the second welding boss and nozzle
• Hot tapping the pipe

Chapter 2. Installing Pipe Nozzles
2.2.1 Identifying and Checking the Nozzle Installation Kit Components, Diametrical
The nozzle kit consists of various components which you must identify and check as described in the following
sub-sections.
The Nozzle Installation Kit contains the materials listed below. Use Figure 4 below to help identify each component.
IMPORTANT: You will need to supply eight 5/8” studs with two nuts each (for 3”, 150# flanges), or 3/4” studs with two
nuts each (for 3”, 300# flanges).
Figure 4: Components in Nozzle Installation Kit
Check the marking on the welding boss. The pipe OD and the mounting angle are engraved on the boss as shown
below.
• 2 Nozzles (if purchased) • 2 Welding bosses • 1 Jig • 1 Threaded rod (1 in. diameter), washer and nut

2.2.2 Selecting and Marking the First Nozzle Location, Diametrical
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
measurement point. Undisturbed flow means avoiding sources of turbulence such as valves, flanges, elbows;
avoiding swirl; and avoiding disturbed flow profiles.
2. We recommend that you install the nozzles on a diameter as near as possible to the horizontal plane
(i.e., 3 o’clock and 9 o’clock positions) for horizontal pipe.
Note: If you cannot find a proper location, please consult with Panametrics Flow Application engineering.
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.

2.2.2 Selecting and Marking the First Nozzle Location, Diametrical (cont.)
3. At the 3 o’clock position, center punch the pipe to mark the position for the center of the first nozzle.
4. Spray this area with a marking dye product. Using a metal edge, scribe 6” long vertical and a horizontal lines that
intersect at the center punch mark.

2.2.3 Determining and Marking the Second Nozzle Location, Diametrical
1. The position for the second nozzle is typically a distance equal to one pipe outside diameter along the pipe and
located on the opposite side of the pipe (i.e., 180° around). Spray this area with a marking dye product. (For
installation other than 45°, the distance is equal to the OD times the tangent of the installation angle.
2. Due to the possible variation in outside diameter of the pipe, measure the outside diameter of the pipe at four
location between the nozzle centers. Calculate the average outside diameter based on these measurements.
3. Using a roll of polyester film (or equivalent), cut a strip of film with the following width and length:
IMPORTANT: Ensure that the sides of the film are cut parallel to each other.
• Width: equal to the average outside diameter calculated in Step 2 above.
• Length: equal to 4 times the outside diameter of the pipe.
