5.3.3 Submenu “Measuring Units”
Use the “Engineering Units and K-Factor Menu” to navigate to “Measuring Units”
menu option. This option allows configuration of the flow meter/controller with the
desired units of measurement. These are global settings and determine what
appears on all process information screens and data log records. Units should be
selected to meet your particular metering needs. A total of 47 different volumetric
and mass-based engineering units are supported (See Table 5.1).
NOTE: Program the Measuring Units first because subsequent
menus may be based on the units selected. Once Flow Unit of
Measure is changed the Totalizer’s Volume based Unit of Measure
will be automatically changed.

5.3.4 “Submenu User-Defined Units”
In addition to conventional flow units user-defined flow engineering units may be
selected. Use the “Engineering Units and K-Factor Menu” to navigate to the
“User-defined Units” menu option. This option enables user-defined configura-
tion of any engineering unit required for process measurement.
The following three parameters are available for this function:
a) UD Unit volume K-Factor (defined in Liters),
b) UD Unit time base (defined in Seconds),
c) UD Unit use density (units with or without density support).
Before using the User-defined Unit, be sure the proper conversion factor of the
new unit with respect to one liter is set (the default entry is 1.00 Liter). Also, prop-
er time base values for User-Defined Units must be set.
