NOTE: The totalizer (total flow measured) will roll over when reaching a certain value.
The maximum value is dependent on the flow units selected (see Totalizer Rollover p.
56).
Selections for flow units are:
SCFM LBS/M MSCFD (MCFD)
SCFH LBS/S SM3/H
NM3/H NLPH MT/H
NM3/M NLPM NM3/D
KG/H MMSCFD (MMCFD) MMSCFM

SM3/D
WARNING!
The F-5500 re-calculates area, 4 and 20mA values, maximum flow for the pulse output
and zero flow cutoff when changing flow units.
NOTE: The totalizer values do not adjust or correct for the new units. When changing
flow units, log the totals in the totalizer and then reset the totalizer after they’ve changed
flow units to maintain accuracy in the totalizer.
