PI AF noise reduction

Hi,

I'm working on a pressure drop measurement analysis in PI AF. However, for my analysis, I first want to reduce the noise and peaks of my trend. This is a PI tag and I want to write the filtered result in a new tag. 

I've tried using the DeltaValue() function to determine an acceptance threshold, as is the case for a bandpass filter, but it only filters the current point and isn't effective on the next, not the rest.

Do you have an idea for a function or analysis to implement?

 

Thank you
