5-5-6 : Setting moving average processing
This function is used to carry out the moving average processing of the measured
flow rate values. The model MCB performs the flow rate calculation every 400 ms.
For example, if the moving average process time is set to 2 seconds, the moving
average processing will be carried out 2 sec./400 ms = 5 times.
If pulsation are generated, this function can be used to suppress the flow rate
fluctuations.
The moving average processing can be given by the following formula:
Example) When the moving average processing is set to 2 sec.:
where
q
k
is a value currently measured, and
Q
k
is a previous output value.
