enhanced with the unique SmartLine Application and
Validation Tool (AVT) found at
https://config.honeywellsmartline.com/. This allows
users to specify their tank level application and the
options desired for their level transmitter. The AVT
intelligently guides the user through the engineering
process and electronically captures and documents
the choices and inputs.

In addition to serving as engineering documentation,

the AVT output also serves as input to the Honeywell
order management system, thus ensuring correct input
of the transmitter model. The additional advantage is a
transmitter with configuration parameters already
specified to match the targeted tank application. Errors
are eliminated and the engineering effort is preserved
from start to finish.
