The DPF60 is a combination
microprocessor-based digital rate
indicator and integrating totalizer.
It accepts inputs of 4 to 20 mA,
0 to 20 mA, 0 to 5 V, or 1 to 5 V and
can be scaled for engineering units
directly from the NEMA 4X (IP66)
rated front panel without tweaking
internal potentiometers. The dual
standard 5 A (@ 250 Vac) relays can
be assigned to the ratemeter, or to
the totalizer, or one relay to each for
batch control and rate alarm.
The display features a floating
decimal point that moves left or right
depending on how many "significant
figures" the user has selected. In the
totalizer mode, 6-digits can be
displayed. The unit is fully scalable
from 0 to 59,999, which indicates the
flow rate represented at 20 mA. A
peak and valley feature allows the
user to call up the recent high and
A square-root extracting input is
optional on all units for use with
differential pressure flowmeters,
such as orifice plates and pitot tubes.
With the DPF66, the user can
toggle between rate of flow and
total flow (6-digits) from the front
panel. The rate display is selectable
for units per second, minute, or hour,
and the totalizer integrates in the
same engineering units. The DPF65
displays just total flow, while the
DPF64 only displays rate of flow.
