  • Page 9: Introduction

    Introduction The C-RL clamp-on ultrasonic flow transducers are used exclusively with the Panametrics Measurement & Control line of ultrasonic flowmeters. These transducers are used to measure the flow of various gases through pipes having diameters from 3/4 in. (20 mm) to 30 in. (750 mm). Such measurements are independent of the pipe material. This manual provides details on the following topics: •...

  • Page 10: Dampening Material

    • The pipe experiences constant condensation on the outside. Note: Consult a Panametrics flowmeter applications engineer or sales engineer if you have any questions regarding dampening material. Details for properly installing the dampening material are discussed later in this manual.

    Installing the C-RL Transducers Panametrics Measurement & Control offers the following transducer mounting fixtures to suit your applications needs: • V1 clamping fixture • V4 clamping fixture • V8 clamping fixture • V12 clamping fixture • PI clamping fixture Figure 2 below and Figure 3 on page 4 show the V1, V4, V8, V12 and PI fixture assemblies. Each type of transducer and fixture requires the installation of dampening material for acoustic isolation.
