Programming
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/off ] – turn on/off interactive command line:
with echo off, 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 flow [1-2] – read the current flow on channel 1 or 2 in GPM .
read flow [1-2] total – read the current total flow 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: flow 1 rate
1: flow 1 total
display urate = [0 .1-10] – set the update rate of the
display, in seconds
Input Channel Configuration
flow [1-2] sensor type = [0-4] – flow sensor type:
0: PulseDI,
1: PulseKFactor,
2: PullupKFactor
3: Analog
flow [1-2] sensor dical k = [x] – DI-type flow sensor k
flow [1-2] sensor dical off = [x] – DI-type flow sensor offset
flow [1-2] sensor kfact = [x] – K factor for non-DI sensors
flow [1-2] sensor analog units = [0-19] – flow units for analog input
flow [1-2] sensor analog range = [0-4] – current range for analog input
flow [1-2] sensor analog high = [x] – flow rate @max current
flow [1-2] sensor analog low = [x] – flow rate @min current
flow [1-2] sensor avg = [0-100] – averaging "time constant," in seconds:
flow [1-2] rate units = [0-19] – flow (channel) rate units to display .
0: GPM
1: gal/s
2: gal/hr
3: Mgal/day
4: L/s
5: LPM
6: L/hr
7: ft3/s
