INSTALLATION GUIDE
18. Fluid Specific Gravity
SP GRAVTY -- Fluid Specific Gravity Entry (Value): Unitless Value
Allows adjustments to be made to the specific gravity (density relative to water) of
the liquid.
As stated previously in the FLUID VI section, specific gravity is utilized in the Reynolds
correction algorithm. It is also utilized if mass flow measurement units are selected
for rate or total.
If a fluid was chosen from the FL TYPE list, a nominal value for specific gravity in that
media is automatically loaded. Revise this value as needed for a given application.
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 is
located in the Appendix of this manual.
19. Fluid Specific Heat Capacity
SP HEAT -- Fluid Specific Heat Capacity (Value): BTU/lb
Allows adjustments to be made to the specific heat capacity of the liquid.
If a fluid was chosen from the FL TYPE list, a default specific heat will be
automatically loaded. This default value is displayed as SP HEAT in the BSC MENU. If
the actual specific heat of the liquid is known or it differs from the default value, the
value can be revised. See Tables 4.1, 4.2, and 4.3 for specific values. Enter a value that
is the mean of both pipes.

20. Transducer Spacing
XDC SPAC -- Transducer Spacing Calculation (Value): ENGLSH (Inches), METRIC
(Millimeters)
Note: This value is calculated by the firmware after all pipe parameters have been entered. The
spacing value only pertains to FST4 and FST5 transducer sets.
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 between the lines scribed into the side of the
transducer blocks.
