Cole-Parmer DAQ with ABB Aquamaster-S Flow Meter

[Aquaman89]

I have a Cole-Parmer 18200-00 DAQ that I'm using to measure the flow rate using an ABB Aquamaster S. The flow meter sends out a pulse that is equivalent to the flow rate in the system. I'm having some trouble writing a program that would give me an accurate flow measurement. I tried converting the pulse into a voltage by using a resistor connected into the analog port but instead of getting a fixed or approximate number for the flow rate I get a range of flows. I'm guessing I should connect the flow meter to a counter port but I don't know how ?

I might even be on the wrong track to beging with. Please Help  ??

I'm attaching the current program I have writtent and the flow settings on the flow meter.

Unless I am confused by your text document, you can simply count pulses.

One pulse means that the pinwheel rotated one time.

They have calibrated one revolution to mean that 1/20th of a Liter has passed.

Therefore, your volume will be:
V = (# pulses) * 1/20

And your flow rate would be:
Q = V / (t2 - t1)

where t is time in whatever units you want.
