*Metric or English units are determined by the setup of the flowmeter.
**Totalizer digits are available for informational purposes only. Respective totals are automatically scaled
by the Tot Digits value selected in the flowmeter setup.
***If the meter is outputting Mole Weight, the unit is "mw", otherwise it is the programmed pressure unit.
VOL_U, TOT_U, MASS_U, MTOT_U and PRESS_U are determined by the units chosen for these measure-
ments in the flowmeter setup. See the instrument User's Manual for the setup of these parameters.
Foundation Fieldbus Communications
Foundation Fieldbus provides a means of communicating with the
flowmeter. The patent numbers which apply are 5,909,363 and
6,424,872.
This Foundation Fieldbus device supports 2 Analog Input (AI)
blocks, which can be configured to supply the following
measurements on the network (see Table D-1 below)..
