Setup > Inputs/Output > Output #1 (or Output #2)
Output #1 and output #2 can operate independently as a frequency, totalizer pulse, direction status or alarm status output
In the
SETUP > INPUT/OUTPUTS > OUTPUT #1 (OR OUTPUT #2) > MODE
menu, select the

Enter the maximum flow rate or velocity frequency that
corresponds to maximum frequency flow rate or velocity Can
be negative to indicate reverse flow The units of
Maximum
match the units in
SETUP > MEASUREMENTS > FLOW UNITS
Example 1:
For a system that only has flow in one direction, the maximum
flow rate is 100 gal/min, and the corresponding maximum
frequency is 2000 Hz, set up the parameters to:
Parameter
Value
Output Source
Flow Rate
Minimum
0 gal/min
Maximum
100 gal/min
Maximum Frequency
2000 Hz
Example 2:
For a system that flow is bidirectional, the flow rate ranges from
-100 gal/min to 100 gal/min and the frequency at 100 gal/min
is 2000 Hz, set up the parameters to:
Parameter
Value
Output Source
Flow Rate
Minimum
-100 gal/min
Maximum

With this setup at
no flow
, the frequency output is 1000 Hz

*POSITIVE FLOW
NEGATIVE FLOW
BIDIRECTIONAL
Select whether the pulse output accumulates only on positive (forward) flow,
only on negative (reverse) flow or anytime flow occurs regardless of the flow
direction (bidirectional) For bidirectional, assign the direction status to the
other output, if desired
SCALING
FACTOR
Numeric entry Units and decimal place based on flow rate selection Default is 1 unit per pulse
Enter the number of totalizer units per pulse The totalizer unit is in the
SETUP > MEASUREMENTS
menu For example, if the totalizer unit is gallons, setting the
PULSES/UNIT
to 10 transmits 1 pulse
every 10 gallons Setting the
SCALING FACTOR
to 0 1 transmits 1 pulse every 0 1 gallons
PULSE
WIDTH
Numeric entry 5…2000 ms Default 50 ms Enter the pulse width in milliseconds
PULSE STATE *PULSE LOW
PULSE HIGH
PULSE LOW
, the pulse totalizer output remains in the off state and the voltage
floats at the source voltage level When the pulse is triggered, the output
turns on and the voltage drops to the low voltage level This setup uses the
least power
If the pulse needs to be at the high voltage level, use the
PULSE HIGH
option
