measurement in pulses through labview

[pirpai]

Hi 

I need some urgent help.I am  measuring the output of my flow meter in pulses per liter. I need to know how to set my daq seetting to give me output in pulses per liter.i tried but it would give me in voltage and a graph for amplitude to time...I need to know the no of pulse per liter so that i can differentiate between a low flow and a high flow of water.I am using RS 257-133 flow meter and a Ni PXI-6070E.Please need asap reply..thanks

Hey Pirpai

Can you describe the input signal a bit better for me. Are you measuring the number of pulses or the magnitude of the pulse in relation to liters. I think if you are measuring the number of pulses you would want to plot the number of pulses per second/minute and that would give you how many liters have flowed in a given period.
