1.1 Overview
The T9 ultrasonic flow transducer is used exclusively with the GE line of ultrasonic flowmeters. These transducers
measure the flow rate of saturated steam and most gases through pipes having diameters between 2 in. (50 mm) and 48
in. (1200 mm). Such measurements are independent of the pipe material. This document provides details on the

1.2 Transducer Construction
Each T9 transducer assembly (see Figure 1) consists of the following components:
•
a metallic body
•
a transducer head that consists of a piezoelectric element wired to the BNC connector
•
a BNC style connector for use in connecting the transducer to the flowmeter
•
an optional noise dampening fitting improves transducer signal transmission.
The T9 transducer has a 180
(40 cm).
