Startup
QUICK-START OPERATING INSTRUCTIONS
C. Apply a single 1/2" (12 mm) bead of couplant grease to the
upstream transducer and secure it to the pipe with a
mounting strap.
D. Apply acoustic couplant grease to the downstream
transducer and press it onto the pipe using hand pressure at
the lineal distance calculated in Step 1.
E. Move the transducer slowly around the mounting area until
the highest signal strength is observed. Secure with a mounting
strap at this location.
DTTS and DTTC Transducers
A. Place the flow meter in signal strength measuring mode.
This value is available on the TFXP display (Service Menu) or
in the Data display of the ULTRALINK™ software utility.
B. The pipe surface, where the transducers are to be mounted,
must be clean and dry. Remove loose scale, rust and paint
to ensure satisfactory acoustical bonds. Grind rough
surfaces of pipes to smooth bare metal. Plastic pipes do not
require preparation other than cleaning.
C. Apply a single 1/2" (12 mm) bead of acoustic couplant grease
to the top half of the transducer and secure it to the pipe with
bottom half or U bolts.
D. Tighten the wing nuts so that the grease begins to flow out
from the edges of the transducer and from the gap between
the transducer halves. Do not over tighten.
4. INITIAL SETTINGS AND POWER UP
A. Press the ON button on the flow meter keypad.
B. From the Service Menu, verify that signal strength is greater
than 2.0%.
C. Input proper units of measure and I/O data.
