Function and features
The flow monitor
• detects flow velocity and temperature in liquid and gaseous
media,
• displays the current flow (LED bar green) or the current temperature
(LED bar red), function is selectable,
• switches the outputs according to the programming:
S1 (pin 4): flow monitoring
Output function

normally closed
S2 (Pin 2): temperature monitoring or logic combination

Due to the calorimetric measuring princple when no flow is present
the temperature of the medium in contact with the sensor can rise.
This can lead to switching of output S2 if the switch point SP
close to the medium temperature.
This can be avoided by setting the switch point slightly higher than the
medium temperature or by setting output S2 to logic function 1.
The specified accuracy of temperature monitoring is only given at a
minimal flow of 5 cm/s (liquids) / 100 cm/s (gases).
