4. Connect power to the transmitter.
5. Enter the following data into the transmitter via the integral keypad or the UltraLink software utility:
1 Transducer mounting method 7 Pipe liner thickness
2 Pipe O.D. (Outside Diameter) 8 Pipe liner material
3 Pipe wall thickness 9 Fluid type
4 Pipe material 10 Fluid sound speed*
5 Pipe sound speed* 11 Fluid viscosity*
6 Pipe relative roughness* 12 Fluid specific gravity*
OTE:N * Nominal values for these parameters are included within the transmitter operating system. The nominal values may
be used as they appear or may be modified if the exact system values are known.
6. Record the value calculated and displayed as transducer spacing XDC SPAC.
Pipe Preparation and Transducer Mounting
DTTR, DTTN, DTTL and DTTH Transducers
1. Place the transmitter in signal strength measuring mode. This value is available on the transmitters display Service Menu or
in the data display of the UltraLink software utility.
2. The pipe surface, where the transducers are to be mounted, must be clean and dry. Remove scale, rust or loose paint to
ensure satisfactory acoustic conduction. Wire brushing the rough surfaces of pipes to smooth bare metal may also be
useful. Plastic pipes do not require preparation other than cleaning.
3. Apply a single 1/2 inch (12 mm) bead of acoustic couplant grease to the upstream transducer and secure it to the pipe
with a mounting strap.
4. Apply acoustic couplant grease to the downstream transducer and press it onto the pipe using hand pressure at the lineal
distance calculated in “Transducer Location” on page8.
5. Space the transducers according to the recommended values found during programming or from the UltraLink software
utility. Secure the transducers with the mounting straps at these locations.
DTTS and DTTC Transducers
1. Place the transmitter in signal strength measuring mode. This value is available on the transmitter’s display Service Menu or
in the data display of the UltraLink software utility.
2. The pipe surface, where the transducers are to be mounted, must be clean and dry. Remove scale, rust or loose paint to
ensure satisfactory acoustic conduction. Wire brushing the rough surfaces of pipes to smooth bare metal may also be
useful. Plastic pipes do not require preparation other than cleaning.
3. Apply a single 1/2 inch (12 mm) bead of acoustic couplant grease to the top half of the transducer and secure it to the pipe
with the bottom half or with U-bolts.
4. Tighten the nuts so the acoustic coupling grease begins to ow out from the edges of the transducer and from the gap
between the transducer and the pipe.
MPORTANTI
Do not overtighten. Overtightening will not improve performance and may damage the transducer.
Initial Settings and Powerup
1. Apply power to the transmitter.
2. Verify that SIG STR is greater than 5.0.
3. Input the units of measure and the I/O data.
