Section 2: Operation preparation and part
replacement notes
2.1 Operation preparation
1. These instructions refer to details and symbols identified on Daniel Measurement and
Control drawing D-08248 (see Appendix C). This operation instruction procedure
applies to T-slot design transducer mount assemblies on Daniel SeniorSonic™
ultrasonic meters only using an extractor tool. The extractor tool uses line pressure to
extract the transducer assembly (J).
2. If line pressure is vented from the meter, the transducer can be removed without using
the extractor tool. See the Daniel Ultrasonic Gas Flow Meter Reference, Installation and
Operation Manual 3-9000-743, for T-slot transducer assembly (J) replacement with line
pressure vented.
3. Always use protective equipment. Proper protective equipment in accordance with the
customer’s regulations and site standard operating procedures is required prior to
operation of the extractor tool. A thorough job safety analysis should be done for all
procedures. Protective equipment may include the following:
• eyewear
• footwear
• hearing protection
• gloves
• hard hat
