Overview
The T17 ultrasonic flow transducer is used exclusively with the GE 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:

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 GE #916-117 Installation Guide.

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 180
