Chapter 3. Acoustic Isolation Installation (FIPA Buffers)

3.1

Introduction

The FIPA Buffer is used for gas applications at lower pressures. This buffer has a flanged isolation section that reduces
acoustic short circuits. The buffer also has a flanged process connection and is typically available in two lengths:

• 2 in. 6 in. for low temperature ranges from -150 to 315

• 6 in. 6 in. for high temperature ranges from -150 to 600
Follow the instructions in this chapter to properly install the buffers and transducers.

Identifying and Checking the Components

CAUTION!
Panametrics supplies the parts required for your installation. Before you begin, check the lists below to make sure you
have all of the needed components. Refer to Figure 7 on page 22 and Figure 8 on page 22 to help you identify each
component.
Note: The list below is for a one-path installation.
• Acoustic Isolation FIPA Buffers - fully assembled
• 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 Junction boxes
• Preamplifiers - required for gas flow applications (may be mounted in transducer junction box)
• 3M epoxy or equivalent for permanent bond (not shown in photo)
• 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
• Tape measure
