Hello
I am a complete newbie. I have just received my new NI 9426 Digital Input Module and it sits in a 8 slot cDAQ-9188.
I have installed Lab View 2012 Signal Express and NI-DAQmx drivers.
I have connected 4 flow meters (open collector) that pulse 263 times per liter.

I have added them in LabView as Acquire Signals and I can see a stream of 0 and 1 on at least one of them. I just used 100 samples and 1k Hertz for now and "Continues Samples". For the other three I am still checking if it's a wiring issue or voltage etc.
What I really don't understand is how to count those edges now. Would I need another software? Is this possible via free software (I am in some sort of 7 day evaluation period). What other software packages are there?
I have used Google and I saw people with the NI9426 have used .vi files to count from flow meters, but I fail to understand if I can use this in LabView or not. As you can tell, I am just a bit puzzled. I wish I would have much more time to read all the documents, but at this moment I am working on a project with a very tight schedule and the most important is to get the counting up and running quickly. At a later stage I will have time to learn more
I have attched the project file, not sure if that would help.
Thanks in advance for any pointers!
Alex
