Chapter 4. Inserting T17 Transducers into the Pipe

Model T17 Installation Guide

4.2.2 Mounting the Insertion Mechanism

1.

Before mounting the mechanism on the isolation valve, refer to

below to familiarize yourself with its

components:

• junction box
• barrel
• packing gland
• transducer

Note:

Explosion-proof boxes may not be mounted on the end of a transducer during shipment.

IMPORTANT:

For an extended range operation meter, the upstream and downstream transducers are different, and it

is crucial to the meter operation that the correct transducer be installed in the correct location. The

upstream transducer has a 180° head, the downstream transducer has a 6° offset, or 174° head, and the

insertion mechanism and transducer have alignment marks.
