Flow Meters
The controller is capable of monitoring 4 DC Flow meters allowing you to monitor the flow through your filters and tank, and
alert you to any possible issues.
If you have the Flow meters displayed on the Home
screen, press that, or if you have it on one of the
Home screen “Docks” press that, and you will see
the screen on the left FLOW METERS.
On this page you see the flow per minute and flow
per hour in either liters or gallons. You can switch
between them by pressing the right-hand bottom
corner.
On the meter is a counter which displays the total
liters or gallons that went through the meter. This is
stored on the SD card every minute so after a restart
it will continue. You can reset the meter by pressing
and holding Reset on the meter for half a second.
*NOTE: The actual meters on the screen display don't have the commas in the counter.
From the Home screen press: Settings > Hardware
> Flow Meters, and you will see the screen to the
left, FLOW METER SETTINGS.
On this page you can select the measurement type,
home page view and a calibration value for each
flow meters. You also see the current amount
flowing so when you adjust things you don't need
to leave the screen.
If you change the measurement type to gallons the
labels and flow will update to match.
Calibrating Flow meters
Most flow meters have an F value, they call that the calibration factor I believe. Typically this is 4.5 but I have seen some
with 5.5. I'm hoping the calibration value is based on that however mine say 4.5 but on the controller I have it set to 4.8.
Not sure if it’s the cheap flow meter or code but it’s best to measure your pump to get a proper value.
The easiest way to do that is get 2 - 5 gallon buckets. Fill one with water and then run the pump for 60 seconds and turn off,
be sure you have the flow meter connected as this could change how much is pumped in 60 seconds. Then measure how
much water was pumped in the bucket. Let’s say you pump 6.2L in that 60 seconds. Now you can run the pump and adjust
the calibration value on this screen until the flow value in L/min matches what you measured.
