MC-III™ EXP Flow Analyzer Appendix D
Note: The registers below should be used with master devices that require the floating point numbers to
be presented with the least significant word first. Their counterparts with floating point numbers in
reverse word order—registers 17011, 17013, 17027 and 17015—are listed in the previous table.

Base Units/Configured Units
The holding register area provides two blocks of registers. The first block is based on the configured units
of measurement. The configured volume units will follow the settings in the Volume Unit register (2000).
The configured rate units will follow the settings in the Rate Volume units (2002) and the Time-Base register
(2003).
For example, if the settings for the volume unit is 2 (BBL), all of the total parameters such as Grand Total
(17011), Daily Total (17015), etc. will be in terms of barrels. The values in these registers will change if the
user changes the units of measurement that appear on the LCD.
The second block is in terms of
base
units. These register values are independent of the configured volume
units in the Volume Unit, Rate Volume Unit, and Time-Base registers. For base units, the time base is always
measured in seconds, and the volume and rate volume units are measured in gallons. If the standard correction
factor has been enabled, the volume unit is standard gallons. The standard gallon is calculated as the gallon
measurement times the Standard Measurement Correction factor (2059). If the x1000 unit is enabled, the
volume unit is gallons times 1000.
Conversion Factors
For base units, the volume unit and rate volume unit is measured in gallons.To convert gallons to another unit
of measure, use the conversion factors listed in the table below. For example, to convert gallons to barrels,
multiply gallons times 0.02380952381.
