he wants us to add "airflow measurement " in the list shown in the image below.

[pavanch]

Yes but even the measurement of airflow is done in volts itself but not in cfm. Iwant the airflow to be measured in cfm just like pressure is measured in psi in pressure bridge in DAQ ASSISTANT.

Then you need to create a scale that converts volts to cfm.  That is the purpose of the custom scaling section to the lower right of the DAQ assistan.

thanks for the response.

I have used that but it is not possible to create a custom scale measurement in DAQ assistant by ourselves is it??

If you have actually used that then you should certainly know that it is possible. Your question is silly.

Did you try clicking on the "Custom Scaling" dropdown? And see the "Create New..." item?

Please try things before asking questions on the forum that can easily be answered by a little effort on your part.

i have tried it guys. What i meant by custom scaling measurement is that can I add my own measurement device  ( air flow measurement) in the drop down list of channelsjust like pressure bridge, LVDT, starin measurement etc.

You aren't paying any attention to the answers and you aren't really paying any attention at all to the DAQ Assistant screen.

dude i totally got u and i tried it. I am asking about having direct airflow measurement in DAQ assisatant not like using sensor voltage signals. I would llike to have direct airflow measurement device added to it is it possible.

What are you talking about?

The data acquisition device reads voltage.  You need to convert voltage to air flow (CFM).  You use the scaling for that channel to accomplish that based on the conversion factors of your sensor that says so many volts equals so many cubic feet per minute.
