1.1 Scope of the document
These instructions are supplementary to the standard product documentation of the signal
converter. The details depicted therein, in particular the safety information are valid and should
be adhered to. The present supplementary instructions provide additional information for the
devices when being operated and connected to a Foundation Fieldbus.
1.2 Device description
Electromagnetic flowmeters are designed exclusively to measure the flow and conductivity of
electrically conductive, liquid media.
Your measuring device is supplied ready for operation. The factory settings for the operating
data have been made in accordance with your order specifications.
The following versions are available:
•Compact version (the signal converter is mounted directly on the flow sensor)
•Remote version (electrical connection to the flow sensor via field current and signal cable)
INFORMATION!
The present supplementary instruction for the signal converter with Foundation Fieldbus
interface, plus the software with the DD and CCF files are included in our scope of supply, in
addition to those items delivered for the standard device.
