Introduction; Transducer Construction - GE CModel C-RS Installation Manual

1. Introduction

The Model C-RS clamp-on ultrasonic flow transducer for liquids is used exclusively with the GE line of ultrasonic
flowmeters. These transducers measure the flow rate of sonically-conductive liquids through pipes having diameters
from 2 in. (5 cm) to over 300 in. (7.6 m). Such measurements are typically independent of the pipe material.

2. Transducer Construction

C-RS transducers may be used at process temperatures from -40 to 302
assembly consists of the following components (see Figure 1):
•
A stainless steel adapter with 3/4" NPT male thread for attaching a junction box
•
A transducer that consists of a piezoelectric element mounted on a wedge and wired to the BNC connector
•
A BNC style connector for use in connecting the transducer to the flowmeter.
Note: The process temperature range specified above is for ATEX certified designs. Consult the factory for higher
temperatures.
