Installation & Operation Manual
USB COMMAND LIST
In the list below, brackets indicate an argument, specifying
its type and value range. For instance [0-18] stands for any
number between 0 and 18 (inclusive).
Example: “display line1 = 1” sets Line 1 of the display to display
#1, which happens to be the totalizer for flow channel 1.
Diagnostics:
id – show model number & software version
echo [on/o] – turn on/o interactive command line:
with echo o, this interface is more
amenable to scripting; it still accepts the
same commands.
Any command entered without an “ = “ sign and
variable will display the current setting.
Example: Typing “display line1” returns “0” which is the
variable for Flow Rate.
read ow [1-2] – read the current ow on channel 1 or 2
in GPM.
read ow [1-2] total – read the current total ow on
channel 1 or 2 in gallons.
DISPLAY CONFIGURATION
display line1 = [0-1] – set line 1 of the display
display line2 = [0-1] – set line 2 of the display
0: ow 1 rate
1: ow 1 total
display urate = [0.1-10] – set the update rate of the
display, in seconds
INPUT CHANNEL CONFIGURATION
ow [1-2] sensor type = [0-4] – ow sensor type:
0: PulseDI,
1: PulseKFactor,
2: PullupKFactor
3: Analog
ow [1-2] sensor dical k = [x] – DI-type ow sensor k
ow [1-2] sensor dical o = [x] – DI-type ow sensor oset
ow [1-2] sensor kfact = [x] – K factor for non-DI sensors
ow [1-2] sensor analog units = [0-19] – ow units for analog
input
ow [1-2] sensor analog range = [0-4] – current range for
analog input
ow [1-2] sensor analog high = [x] – ow rate @max current
ow [1-2] sensor analog low = [x] – ow rate @min current
ow [1-2] sensor avg = [0-100] – averaging "time constant," in
seconds:
ow [1-2] rate units = [0-19] – ow (channel) rate units to
display.

19: Custom
ow [1-2] rate ndigits = [2-10] – number of decimal places to
show for ow rate
ow [1-2] rate custom label = [string] – set the label for custom
units
ow [1-2] rate custom conv = [0-100] – conversion factor for
custom units
ow [1-2] total units = [0-7] – set the totalizer units to display
0: gal
1: Mgal
2: L
3: ft3
4: m3
5: acreft
