reading frequency data from a flowmeter

[Navidvd_]

Hi there,

I want to read the frequency data from a flowmeter (Krohne Batchflux 5500C), which comes with a frequency output and convert it to flow rate data. I am using USB-6421. As I am relatively new to LabVIEW, I would appreciate it if anyone could help me with this.

Thanks

Navid

Take those Training resources offered in the header of the LabVIEW board.

Then open the example finder and search for the DAQmx counter input example VIs.

That should get you started with a simple frequency measurement!

Once you know the frequency you can apply simple math to convert to your desired flowrate, the equation should be given in the sensor manual…

Hi,

Thanks for your response. I checked the examples, and I can see I can either choose frequency or count edge options. I did some readings, and it seems that counting edges over a time window would be more accurate. Can you please let me know which approach you think is more appropriate?

Thanks

Navid
