Dynasonics TFXP Series Transit Time Ultrasonic Flow Meter - Manual (Page 49)

Rev. 5/09
-3.11- TFXP
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 in the Appendix
of this manual.
SP HEAT -- Fluid Specific Heat Capacity (Value)
(only visible when RTD Module is activated)
Nominal Heat Capacity
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 Basic 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 3.1, 3.2, 3.3 and 3.4 on pages 3.11 and 3.12 for specific
values. Enter a value that is the mean of both pipes.
