10%.
All models flowmeter supply rated
@ 25 mA max.
All models selectable for 24, 10, or 5 VDC
supply (Internal J4 jumper).
Low Voltage
Mag Pickup
(Isolated) Sensitivity: 40 mVp-p to 8Vp-p
Minimum
Input
Frequency 0.001 Hz
Minimum frequency is dependent on high
gate setting.
Maximum

Input
Threshold Low High
1.6 V 3.3 V
Accuracy ±0.03% of calibrated span ±1 count
Temperature
Drift Rate display is not affected by changes in
temperature.
Multi-Point
Linearization 2 to 32 points
Low-Flow
Cutoff 0.1 to 999,999 (0 disables cutoff function).
Point below at which display always shows
zero.
Decimal Point Up to five decimal places or none:
d.ddddd
,
d.dddd
,
d.ddd
,
d.dd
,
d.d
, or
dddddd
Calibration May be calibrated using K-factor, internal
calibration, or by applying an external
calibration signal.
K-Factor Field programmable K-factor converts input
pulses to rate in engineering units. May be
programmed from 0.00001 to 999,999
pulses/unit.
Calibration
Range Input 1 signal may be set anywhere in the
range of the meter; input 2 signal may be set
anywhere above or below input 1 setting.
Minimum input span between any two
inputs is 0.10 Hz.
An error message will appear if the input 1
and input 2 signals are too close together.
Filter Programmable contact de-bounce filter:
40 to 999 Hz maximum input frequency
allowed with low speed filter.
Time Base Second, minute, hour, or day
Gate Low gate: 0.1-99.9 seconds
High gate: 2.0-999.9 seconds
Rate/Totalizer
Display
Assignment Display lines 1 & 2 may be assigned to
rate, total, grand total, alternate rate/total,
alternate rate/grand total, set points,
alternate rate/units, alternate total/units,
alternate grand total/units, display Hi,
display Lo, display Hi/Lo, display Modbus,
display units (line 2) and display off (line 2).
Rate Display
Indication -99999 to 999999, lead zero blanking.
“R” LED illuminates while displaying rate or
frequency.
Total Display
& Total
Overflow 0 to 999,999; automatic lead zero blanking.
“T” LED is illuminated while displaying total
or grand total.
Up to 999,999,999 with total-overflow
feature. “
oF
” is displayed to the left of total
overflow and
▲ LED is illuminated.
Alternating
Display Either display may be programmed to
alternate between rate and total or rate and
grand total every 10 seconds.
Total
Decimal Point Up to five decimal places or none:
d.ddddd
,
d.dddd
,
d.ddd
,
d.dd
,
d.d
, or
dddddd
Total decimal point is independent of rate
decimal point.
Totalizer Calculates total based on rate and field
programmable multiplier to display total in
engineering units. Time base must be
selected according to the time units in
which the rate is displayed.
Totalizer
Rollover Totalizer rolls over when display exceeds
999,999,999. Relay status reflects display.
Total
Overflow
Override Program total reset for automatic with 0.1
second delay and set point 1 for 999,999
Totalizer
Presets Four, user selectable under setup menu.
Any set point can be assigned to total and
may be programmed anywhere in the
range of the meter for total alarm
indication.
Programmable
Delay
On Release 0.1 and 999.9 seconds; applied to the first
relay assigned to total or grand total.
If the meter is programmed to reset total to
zero automatically when the preset is
reached, then a delay will occur before the
total is reset.
Total Reset Via front panel button, external contact
closure on digital inputs, automatically via
user selectable preset value and time
delay, or through serial communications.
Total Reset
Password Total and grand total passwords may be
entered to prevent resetting the total or
grand total from the front panel.
Non-
Resettable
Total The grand total can be programmed as a
non-resettable total by entering the
password “050873”.
Non-Volatile
Memory Total and Grand Total values, and all
programmed settings are stored in
non-volatile memory for a minimum of ten
years if power is lost.
•
Once the Grand Total has been programmed as
“non-resettable” the feature
CANNOT be
disabled.
