Function
Rate: Linear (2-32 points), square root, or
programmable exponent
If the totalizer is disabled, PV1 and PV2: Linear
(2-32 points) or round horizontal tank
Low-Flow
Cutoff
0.1 to 999,999 or disable. Point below at which
the display always shows zero.
HART
Transparency
The meter does not interfere with existing
HART communications; it displays the
4-20 mA primary variable and it allows the
HART communications to pass through
without interruption. The meter is not affected if
a HART communicator is connected to the
loop. The meter does not display secondary
HART variables.
Rate/Totalizer
Rate Display
Top display: -9999 to 99999;
Bottom display: -9,999,999 to 99,999,999

Total & Grand
Total Display
Top display: 0 to 99999;
Bottom display: 0 to 99,999,999
(with commas)
13-Digit Total
& Grand Total
Up to 9,999,999,999,999 using both lines
with 13-digit total feature enabled.
Total Decimal
Point
Up to four decimal places on top, up to seven
decimal places on bottom. Total decimal
point is independent of rate decimal point.
Totalizer
Calculates total based on rate and rate units
to display total in engineering units. A custom
factor must be programmed if using custom
defined units.
Time Base
Seconds, Minutes, Hours, Days
Totalizer
Rollover
Totalizer rolls over when display exceeds
99,999,999 (9,999,999,999,999 if 13-digit
limit enabled). Relay status reflects display.
Total & Grand
Total Reset
Via CapTouch button, external contact
closure on digital input, or MeterView XL.
Total & Grand
Total Reset
Passwords
Total and grand total passwords may be
entered to prevent resetting the total or grand
total unless a password is entered.
Non-
Resettable
Grand Total
Grand total reset may be disabled through
the meter interface. Grand total reset may be
permanently disabled by selecting
YES
at the
PERMLOCK
menu.
•
Once the Grand Total has been programmed as
“non-resettable” the feature
CANNOT
be disabled.
Non-Volatile
Memory
Total and Grand Total values are stored in
non-volatile memory for a minimum of ten
years if power is lost.
