10 Applications and functions
VEGAMET 342 • 4 … 20 mA
63731-EN-221107
Select application
Select the application " Screen control " from the options offered.
Assign measuring loop name
Assign a unique designation to the measuring points so that there can
be no confusion with other measuring points.
Sensor characteristic values - define measuring point 1
The measuring range suitable for the application should be set di-
rectly in the sensor to achieve the maximum accuracy. This measuring
range must now be stored once again in the assistant together with
the sensor type and measuring unit.
Sensor characteristic values - define measuring point 2
The measuring range suitable for the application should be set di-
rectly in the sensor to achieve the maximum accuracy. This measuring
range must now be stored once again in the assistant together with
the sensor type and measuring unit.
Adjustment values - define measuring point 1
Enter the adjustment values of the measuring point for 0 % and for
100 %.
Adjustment values - define measuring point 2
Enter the adjustment values of the measuring point for 0 % and for
100 %.
Scaling - define measuring point 3
Enter the desired measured value, measuring unit and display format
and the appropriate scaling values for 0 % and 100 %.
Configure relay switching points
Enter the relay switching points at which the pumps should be
switched, here.
Configure measured value indication
In the last step you can configure which and how many measured
values are to be shown on the display. In addition, you can define
the base of the display value, the display format and the optional bar
graph.
10.4 Flow measurement flume/weir
Waste water and rainwater are often transported to the sewage treat-
ment plant in open collection channels. The flow rate is measured at
various points in the collection channels. For flow measurement in
open waters, a constriction or a standardised channel must be used.
This constriction creates a certain backwater depending on the flow
rate. The flow rate can now be derived from the level of this backwater.
The current flow rate is shown on the display in the selected unit of
measurement (e.g. m
3
/h). In addition, the flow rate is made available
via the current output and can thus be further processed by down-
stream devices.
