Equip the unit with suitable protection (e�g� cover) to avoid hazard to person-
nel from leaking media�
3 Functions and features
The unit monitors liquid media (water, glycol solutions, industrial oils, coolants)�
It detects the two process categories volumetric flow or medium temperature�
4 Function
• The unit detects the volumetric flow quantity based on the principle of differen-
tial pressure�
• The unit features an IO-Link interface and is designed for full bidirectional
communication�
• The unit displays the current volumetric flow quantity or temperature� It gener-
ates 2 output signals according to the parameter setting:
OUT1/IO-Link: 4 selection options
Parameter setting
-Switching signal: limit values for volumetric flow
quantity
-or switching signal: limit values for temperature
OUT2: 2 selection options
Parameter setting
-Analogue signal for volumetric flow quantity
-or analogue signal for temperature
4.1 Switching function
OUT1 changes its switching status if it is above or below the set switching limits
(flow or temperature)� Hysteresis or window function can be selected� Example of
volumetric flow monitoring:
