4.1 Processing of the measured signals

The unit generates 2 output signals according to the parameter settings:
OUT1/IO-Link: 4 selection options

Parameter setting

-Switching signal for volumetric flow quantity limit

→ 10.2.1

-Pulse signal for quantity meter

→ 10.3.1

-Switching signal for preset counter

→ 10.3.2

-Switching signal for direction of flow

→ 10.2.4

OUT2: 6 selection options

Parameter setting

-Switching signal for volumetric flow quantity limit

→ 10.2.2

-Switching signal for temperature limit

→ 10.4.1

-Analogue signal for volumetric flow quantity

→ 10.2.3

-Analogue signal for temperature

→ 10.4.2

-Switching signal for direction of flow

→ 10.2.4

-Input for external counter reset signal (InD)

→ 10.3.7

4.2 Direction of flow

In addition to the flow velocity and the volumetric flow quantity, the unit also de-

tects the direction of flow�

4.2.1 Determination of the direction of flow (Fdir)

An arrow with the text "flow direction" on the unit indicates the positive flow direc-

tion� The flow direction can be inversed

(→ 10.5.9)

�

►

Use the supplied label to mark the changed flow direction (new positive

direction of flow)�

Flow...
