CAUTION
For medium temperatures above 50 °C (122 °F) some parts of the housing can
heat up to over 65 °C (149 °F)� Risk of burns�
► In this case do not touch the unit�
► Protect the housing against contact with flammable substances and uninten-
tional contact�
► Do not press the pushbuttons manually; instead use another object (e�g�
ballpoint pen)�
3 Functions and features
The unit monitors water-based fluids (water, deionised water, cooling water)�
It detects the two process categories volumetric flow and medium temperature�
Pressure Equipment Directive (PED):
The units comply with the Pressure Equipment Directive and are designed
and manufactured for group 2 fluids in accordance with the sound engi-
neering practice� Use of group 1 fluids on request�
4 Function
• The unit detects the volumetric flow quantity based on the Vortex measuring
principle�
• It features an IO-Link interface�
• The unit displays the current flow and temperature� It generates 2 output
signals according to the parameter setting:
-OUT1 / IO-Link: Analogue signal for temperature
-OUT2: Analogue signal for volumetric flow quantity
