This manual contains detailed operating instructions for all aspects of the DFX flow instrument The following condensed
instructions are provided to help you get the instrument up and running as quickly as possible This pertains to basic
operation of the clamp-on transducer only If specific instrument features, a hazardous area installation or an alternate
transducer style are to be used—or if you are unfamiliar with this type of instrument—see the appropriate section in the
manual for complete details

Pipe Preparation and Transducer Mounting
1 The piping surface, where the transducers mount, needs to be clean and dry Remove loose scale, rust and paint for
satisfactory acoustical bonds
2 Connect the mounting straps around the pipe Leave the strap loose enough to slip the transducers underneath
3 Apply a liberal amount of couplant grease onto the transducer faces
4 Place each transducer under the mounting strap, 180° apart on the pipe Verify that the transducer cables are facing the
same direction on the downstream side of the flow See
5 Route the transducer cable back to the monitor, avoiding conduits that contain high voltage AC supply wires
