Hi there
If you can see the LED blinking it means that your sensor is operating corectly. If you can not pass the data to LV (or you can sometimes) it means that you have a problem with dealing with DAQ itself. IT is hard to say more not knowing your setup.
About the speed. I understand you want to disply the angular velocity, i.e. the number of rotations per second, rigt?
If you have three pulses per rotation, so provided the time between pulses "tp", the the instantenous angular velocity will be:
f=1/(3*tp) [rev/sec];
or
W=2*pi/(3*tp) [rad]
You may also average the tp over several readings if you want.
take care
