T5 Flare Gas Transducer Installation Guide 1

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 90

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 45

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
