Connect Magview flowmeter to USB6009

[hamzawy47]

Hi, I am still very new to LabView and DAQs, and have been trying to connect magview MVM-002-Q to a USB6009 DAQ card, but unfortunately with no success. The connections I made are similar to the one shown in the data sheet, using PFI and the +5V pins with the GND as well. But I am not sure how can I read the frequency. I tried using MATLAB but with no success. I even tried with DAQmax test option when it first opens, but it keeps showing 0 count. Should I build a labview program for it? If yes, how can I start? I would appreciate any kind of help.

Best,

Hamza

How did you do the wiring? Can you share your wiring diagram?

How you tried to capture the pulse output from the sensor using a scope?

I can see a pulse using a oscilloscope. However I believe I need to build a labview program to be able to read it. Do you have any suggestions on how to start? or if there are some examples?

You should start with Using Test Panels in Measurement & Automation Explorer for Devices Supported by NI-DAQmx

Once the acquisition is working with the test panel, you can go ahead with programming. The LabVIEW examples are available at Help >> Find Examples... >> Hardware Input and Output >> DAQmx

I found out a solution. The reason why I was not detecting any output on Labview. The output voltage was higher than the maximum detectable voltage by my daq card, thus i needed to add an extra resistor in parallel.
