I have a Senic sonic level sensor which outputs a 4-20 mA signal based on level. The sensor reads the level of a 1400 gallon tank. This signal goes into one channel of a F2-08AD-1 analog input card for on a dl250 system. I used the v memory location to display the level in gallons on a C-more screen. The sensor tends to jump around a little which makes my screen display number jump around. I am looking for ideas on how to make the read out a little more stable. Perhaps there is a way to display an "average " tank level reading that updates periodically rather than constant? Any suggestions? Thanks.

You will have to do the filtering/averaging in the PLC program. Then display the result.

try using the FILTERB instruction... this will allow you to filter the binary data so it isn't 'jumpy '
