What is an Image
File?
An image file is
a EPROM code that allows the flow computer to perform a certain task (liquid
measuring, gas measuring, prover testing, etc.)
The
image file is only downloaded when an application upgrade is needed.
When an image file
is downloaded to the flow computer, all the information in the computer is lost
(configuration and historical data). Make sure to retrieve all the important
information from the flow computer before changing the image file.
How to download
an Image File?
You can download
the image file by either using our Downloader software or through any of our
Dynacom applications.
