Product overview
The display filter only affects the flow rate measured value in SHOW mode [AVER].
4.2.5
Analogue output
Analogue signal
The signal of the analogue output can be assigned the physical measured variables of flow rate or
temperature. The physical measured value of flow rate is configured as standard.
Output signal
The analogue output can be configured either as voltage output 0 ... 10 V oder 1 ... 5 V or as current
output 4 ... 20 mA. By default the voltage output is set to 0 ... 10 V.
Scaling of the analogue signal
The default setting for the analogue output signal is 0 ... 10 V, 1 ... 5 V or 4 ... 20 mA for the complete
sensing range "Full Scale (FS)". If only part of the sensing range is to be used, the analogue value
output can be scaled to the partial range.
The analogue output can also be scaled in the negative range up to -100%FS.
Scale 0%/100% (default)
Scale 20%/80%

4.2.6
Security code
A 4-digit numeric code can be set to protect the device settings from unauthorised access. The
security code must be entered in EDIT mode and TEACH mode when changing settings.
The IO-Link interface offers additional options for blocking access è 8 IO-Link interface description.
4.2.7
Minimum value and maximum value
The minimum values and the maximum values for the flow measurement or the temperature measure-
ment are displayed and reset in the SHOW mode.
The minimum and maximum values are reset when the operating voltage is switched off.
4.2.8
Replication of the parameters
This function enables all settings that have been carried out on one sensor (master) to be transferred
to other identical sensors (device).
