Hi saitej,

set up a DAQmx counter task and count the pulses. Then calculate the change of pulses per time interval…

Use the example finder to find a suitable example VI!

Start LabVIEW.  Click on Help.  Click "Find Examples ...".  In the Search box, type "Pulse".  Follow the directions.  Use your Common Sense to choose a few Examples to examine.  Read, study, and try out the examples.  Adapt them to suit your situation.

Before searching the examples, be sure to limit them to your hardware. You don't want to find something that won't work on the basic DAQ device that you have.
