16 CFM WITH NO MOTORS TURNED ON

[HIGHOCTAIN2000]

I built a flow bench with pts plans this past winter ben very happy with it used it a lot at first, then other things took up my time so I did not use it for a couple months , now when I try to use it my computer soft ware says I have 16 cfm of air flow with no motors turned on. if I power down the dmm it will say zero briefly then climb back to 16 cfm ,air flow test pressure says 0 any thoughts.

If you're using the pts dm this is very normal. Check in the dm area of the forum for the reasons. If you aren't using a pts, we need a bit more information.

Power the DM up and let it set for a couple hours if it does not settle down contact Bruce through a PM and he can help you calibrate.
