Device functions

Flow monitoring

The main function of the device is the monitoring of the flow rate. The flow
rate is measured by a calorimetric sensor in a pipe; the actual flow status is
displayed via a LED-band; it is also sent via a communication signal – when
connected to an IO-Link- or HART®-Master.
The device versions with switching output (Out 1 (Flow)) for flow monitoring
change their switching status when the set switchpoint has been reached with
an increasing flow rate. If the flow rate decreases, the switching status changes
when the switchpoint is underreached by the hysteresis. In addition, upper and
lower limits of the display range for flow monitoring can be set.
The device versions with current output for flow monitoring are only indicating
the actual flow within the teachable display range.
