I have a new Flexim Ultrasonic flow meter that shows flow and other variables (sounds speed, etc.) locally, but in AMS and DeltaV (14.3.1) shows "bad sensor failure". Only temperature and signal strength show "Good". All the other variables, including standard volumetric flow rate, show "bad". Any idea what I am doing wrong? The DD I downloaded from the Emerson website would not load, however the one that was on the media supplied by Flexim loaded okay and I was able to commission the device. I can configure an AI for temperature and it works fine, but flow rate still shows "bad sensor failure". Any thoughts?

In reply to John Rezabek:
This issue is solved. A factory representative remembered that for the Fluxus G704, fieldbus AI blocks don't connect to the normal measurement channels ("A" and "B") but to the computational channels. The manual is a little misleading in that it states the computational channel ("Y") is only used with dual channel applications (where dual sensor tracks are e.g. averaged for a more accurate flow measurement). Ours is a single channel. So, channel "Y" needed to be enabled (locally - no way to do this through the DD or the DTM*) and its equation set to "(A + A)/2" . . .
*Indeed I installed the DTM that was on the media that shipped with the meter; used AMS to add it to the catalog and it became an option in the right-click context menu for the instrument. Interestingly - there was nothing you could do with the DTM that you couldn't do with the normal AMS "Configure" EDDL dialog. There are so many parameters and options in instruments like this - it would be great to access them from the system vs. locally.
