Modifications to devices with SIL capability onsite at the user's plant are possible following
approval by the Endress+Hauser manufacturing center. In this case, the modifications must
be performed and documented by an Endress+Hauser service technician.

4 Automation system
An analog signal (4–20 mA) proportional to the volume flow is generated in the transmitter.
This is sent to a downstream automation system where it is monitored to determine whether
it falls below or exceeds a specified limit value. The safety function (volume flow monitoring)
is implemented in this way.
