Linear Flow Factor
The
Linear Flow Factor
enables the sensor to be matched to a reference flow in the
application.
This menu is only available when
Velocity relative (%)
,
Velocity absolute
or
Volume flow
and counter
is selected in the
Measurement Mode
menu.
You can use the special adjustment to change the curve slope of measured values. The
slope is specified as a percent. You can select a value between 50% and 150% for this
factor. The factory setting is 100%.
The
Linear Flow Factor
affects the process data. This option is not available after a
teach-in has been performed for flow.

Empty Detect Factor
The
Empty Detect Factor
can be used to adjust the response time of the empty pipe
detection. You can select a value between 70% and 140% for this factor. The factory
setting is 100%. The higher the empty detect factor, the faster the response time. This
means that the empty pipe detection will react more sensitively to any level fluctuations
in the pipe and Q1 will also switch if the sensor tip is only uncovered for a short time. To
avoid this, the response time can be increased by reducing the empty detection factor.
