Function and features

The flow monitor monitors liquid media. It senses whether there is a
preset flow (= medium flows) or not (= medium does not flow) and
provides a switching signal.
Installation
The sensor tip must be completely immersed in the medium.
• In the case of horizontal pipes mount the unit from the side, if pos-
sible (fig. 1).
When the unit is to be mounted at the bottom of the pipe, it should
be free from deposits.
When the unit is to be mounted at the top of the pipe, it should be
completely filled with the medium to be monitored.
• In the case of vertical pipes mount the unit in a place where the
medium flows upwards (fig. 2).
D = 15mm for units with M12 x 1 and 1/4" thread
D = 23mm for units with 1/2" thread.
