I'm measuring liquid volume using a flow sensor that outputs pulses
from 1Hz to 16Hz.
The uP measures the time between pulses and do a 32 sample majority
filter. This type of filter gives me two different time constants, one
when the frequency is rising and another when it is falling.
I need one reading every second.
Is there any better way of filtering those samples?
How the filtering would have to be done with these type of signals?
Thanks.
