2. PIPE PREPARATION AND TRANSDUCER MOUNTING
A. The piping surface, where the transducers are to be
mounted, needs to be clean and dry. Remove loose scale,
rust and paint to ensure satisfactory acoustical bonds.
B. Apply a ¼" (6 mm) wide bead of couplant, lengthwise onto
the transducer faces. Place the single DTTS/DTTC
transducer or each DTTN/DTTH transducers onto the pipe
ensuring proper linear and radial placement
.
C. Tighten the transducer mounting straps sufficiently to
squeeze the couplant out along the flat surface of the
transducer, filling the void between the transducer and the
pipe wall. Small pipe transducers using wing nuts should be
hand tightened only.
3. TRANSDUCER/POWER CONNECTIONS
A. If additional cable is to be added to the transducers, the cable
must be the same type as utilized on the transducer and both
cables must be of equal length.
B. Refer to the wiring diagram located on the inside of the TFXL
cover and Figure 1.4 on page 1.10 for proper power and
transducer connections. Verify that the voltage level listed on
the product identification label - located on the side of the
instrument enclosure - matches the power source where
connection is being made.
4. INITIAL SETTINGS AND POWER UP
A. Apply power to the instrument.
B. Verify that SIG STR is greater than 7.
C. Verify that measured liquid SSPD is within 0.5% of the
configuration value.
D. Input proper units of measure and I/O data.
