Application of Couplant
For DTTN, DTTL, and DTTH transducers, place a single bead of couplant, approximately 1/2 inch (12 mm) thick, on the flat
face of the transducer. See Figure 12 . Generally, a silicone-based grease is used as an acoustic couplant, but any grease-like
substance that is rated not to “flow” at the temperature that the pipe may operate at will be acceptable. For pipe surface
temperature over 130° F (55° C), Sonotemp® (P.N. D002-2011-010) is recommended.
