DTTS transducer designation refers to both DTTS and DTTC transducer types.
Table 3: Transducer mounting modes — DTTS / DTTC
For pipes 24 inch (600 mm) and larger the DTTL transducers using a transmission frequency of 500 kHz are recommended.
DTTL transducers may also be advantageous on pipes between 4…24 inches if there are less quantifiable complicating
aspects such as – sludge, tuberculation, scale, rubber liners, plastic liners, thick mortar, gas bubbles, suspended solids,
emulsions, or pipes that are perhaps partially buried where a V-mount is required/desired, etc.
