Chapter 2. Standard Installation (FTPA Buffers)
2.1 Introduction
The FTPA Buffer is used for both liquid and gas applications. The buffer has a flanged process connection and is
typically available in two lengths:
• 2 in.

6 in. for low process temperature ranges from -150 to 315
o
C (-270 to 600
o
F)
• 6 in.

6 in. for high process temperature ranges from -150 to 600
o
C (-270 to 1,100
o
F)
IMPORTANT: The buffer ensures that the service temperature of the transducer remains at ambient.
Use the sections that follow to properly install the buffers and transducers.
2.2 Identifying and Checking the Components
Panametrics supplies the parts required for your intended installation. Before you install the FTPA Buffer, check the
lists below to make sure you have all of the needed components. Refer to
Figure 5 on page 10 and Figure 6 on page 10
to help you identify each component.
Note: The list below is for a one-path installation.
• 2 FTPA buffers
• 2 BWT1 transducers
• 2 Kamprofile gaskets
IMPORTANT: Kamprofile gaskets must be used for two reasons: they ensure a leak tight seal and they provide
necessary acoustic isolation.
• 2 Mating lap - joint flanges
• 2 Junction boxes
• Preamplifiers - required for gas flow applications (may be mounted in transducer junction box)
• 3M epoxy or equivalent (for permanent bond)

• Required studs, nuts and washers
(not shown in photo)
• 10 ft (3 m) Coaxial cable with BNC connectors (not shown in photo)
• Additional preamplifier to electronics cable (required for gas flow applications)
(not shown in photo)
You will need to supply the following additional items:
• Copperslip (SS316), Molykote grease P47 (CS) or equivalent anti-seizing compound
• Adjustable torque wrench with 15
- 148 ft-lb range (20 - 200 N-m) with socket drive
• Standard and deep sockets
• Adjustable wrench (12 in. long or equivalent)
• Steel wool
• Calipers
CAUTION!
It is critical that you follow the instructions outlined in this document. If you do not,
Panametrics cannot ensure the proper operation of your equipment.
