Hi Experts, the pulses counted in my flow meter are not the same with what it counts in my PLC.

Hi experts, the pulses counted in my flow meter are not the same with what is counted in my PLC.

my flow meter is set at 1 liter per pulse, and the pulse width is 100 mili-seconds 

my PLC filter is set at 5 micro-seconds.

example for 12-13 seconds in my flow meter readings 23 liters will be dispense

for the same 12-13 second it shows 12 liters dispensed on my HMI.

please what settings are required to make both the PLC and flow meter count the same ?

am using high speed counter for this application.

Please i will appreciate any contribution to enable me solve this problem 

thanks
