Setting Description
Channel
1,2,3,4
Assignment of available channels for connected sensors.
> Select desired channel (analog input) from drop-down list.
Value
HWater,
HAir,
None
> Select the connected external water level sensor type for preselected channel from drop-down
list.
Always connect the external water level sensor on channel 1.
As value always choose HWater for channel 1.
This water level sensor can be selected for discharge calculation in the main menu under
Parameter Water Level as H (Extern 1).
HWater: External water level sensor connected on channel 1.
HAir: If a second water level sensor is connected on channel 2, 3 or 4, then choose HAir as value.
None: No analog sensor is connected.
Settings
Measurement
Select the method of water level measurement (water level / distance).
Measurement
Waterlevel
The sensor measures the water level from bottom to water surface
(height of water column).
The user defined water level range of the selected sensor is proportional to the input current
range.
Example: 0…10 m water level measuring range
0/4 mA corresponds to 0 m water level and 20 mA corresponds to 10 m water level
OTE: N Choose this option for parameterization of all water level sensor types provided by the
manufacturer. Even if non-contact sensors are used, the distance values are converted
to water level values by the sensor.
W max > Enter max. water level value for max. current input value:
Example: water level measurement range 0…10 m:
20 mA corresponds to 10 m water level
Select corresponding unit for water level (length).
W min >Enter min. water level value for min. current input value:
0 mA corresponds to 0 m water level
Select corresponding unit for water level (length).
Measurement
Distance
The water level sensor is mounted above water surface and measures the distance from sensor
surface to the water surface. In this case, a high water level means a smaller distance to the
sensor and vice versa.
Example: distance measuring range 0…10 m:
0 mA corresponds to 0 m distance (= 10 m water level)
20 mA corresponds to 10 m distance (= 0 m water level)
max Distance > Enter max. distance value for the min. current input value:
Example for 0…10 m water level measuring range:
0 mA corresponds to 10 m distance (= 0 m water level)
Select corresponding unit for distance (length).
min Distance > Define min. distance for max. current input value:
20 mA corresponds to 0 m distance (=10 m water level)
Select corresponding unit for distance (length).
