Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
GE Measurement & Control is an active participant in Europe’s
Waste Electrical and Electronic Equipment
(WEEE)
take-back initiative, directive 2012/19/EU.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the
natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle
most of the materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional
waste administration.

Model C-RL Installation Guide 1
1 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:
• Transducer construction
• Dampening material
• Installation
• Maintenance
• Specifications
2 Transducer Construction
A transducer assembly includes a 316 stainless steel housing with a plastic wedge attached and a BNC-type
electrical connector. The transducer features both integral 3/4” NPT-M threads for mounting a junction box and
integral 5/8-24 UNEF threads for mounting a submersible connector if desired (see
Figure 1
below).

3 Dampening Material
Panametrics Measurement & Control strongly recommends applying DMP dampening material in all permanent
clamp-on applications to help eliminate noise. The following dampening materials are available:
•DMP-1 is a self-adhesive sheet for applications up to 200°F (93°C): The material comes as two 9.5-in. (24 cm)
wide sheets cut in sufficient length for your application. (Length twice the circumference of the pipe at the
installation site.)
•DMP-3 is a compound for applications over 150°F (65oC). The compound is applied to the pipe with a putty
knife.
• The
Pipe Dampening Jacket
(PDJ) is a sheath/jacket with DMP-3 pre-applied to the inside and is also used for
applications over 150oF (65oC). The PDJ is available for pipes 4”, 6”, 8”, 10” and 12” (100, 150, 200, 250 and 300
mm) in diameter.
At a minimum, you should consider applying dampening material if you have any of the following conditions:
• The distance from the nearest butt weld or pipe flange is less than 10 ft (3 m).
• The pipe size is under 16 in. (400 mm) diameter and the gas pressure is 200 psig (1378 kPa) or lower.
• The pipe is deformed (non-circular).
• The pipe is old, with a history of scaling or rust.
• 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.
