Dynasonics TFXM Series Ultrasonic Multi-Channel Flow Meter - Manual (Page 49)

If a fluid was chosen from the FL TYPE list, a nominal value for
specific gravity in that media will be automatically loaded. If the
actual specific gravity is known for the application fluid and that
value varies from the automatically loaded value, the value can
be revised.
If OTHER was chosen as FL TYPE, a SP GRVTY may need to
be entered if mass flows are to be calculated. A list of alternate
fluids and their associated specific gravities are located the
Appendix located at the back of this manual.
XDCR SPAC -- Transducer Spacing Calculation
ENGLSH (Inches)
METRIC (Millimeters)
This value represents the one -dimensional linear measurement
between the transducers (the upstream/downstream
measurement that runs parallel to the pipe). This value is in
inches if ENGLSH was selected as UNITS; in millimeters if
METRIC was selected. This measurement is taken from the
line which is scribed into the side of the transducer block.
If the transducers are being mounted using the transducer
track assembly, a measuring scale is etched into the track.
Place one transducer at 0 inches and the other at the
appropriate measurement.
PART 3 - KEYPAD CONFIGURATION
NOTE: If V-mounting is used on pipes that are smaller than 2
inches [50 mm], the transducers will be mounted "nose-to-
nose" as illustrated in Figure 3.2.
