SP GRVTY -- Fluid Specific Gravity Entry
unitless
Allows adjustments to be made to the specific gravity (density)
of the liquid.
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 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 measure-
ment 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 which
are scribed into the side of the transducer blocks.
PART 2 - TRANSDUCER POSITIONING
Important note for pipe sizes under 2 inches [50 mm]. If the
transducer spacing that is calculated is lower than 2.65 inches
[67 mm], enter W-mount as the transducer mount method or
enter V-mount and place the transducers at 2.65 inches [67
mm]. See Page 3.11 for additional details.
