The
most important part WLM - SYSTEM ... |
|
|
The WLM - Sensor
combines an inductive flow - meter, a piezzo noise microphone and a
piezzo pressure sensor at once. The probe is installed at 11 % of the
inner diameter where there is the mean velocity..

Another important
part of the maintenance - free sensor is the integrated electronic.
It includes the necessary control elements for the sensor as well as
a logger for the data storing. A CPU calculates the significant values
for each measuring point and manages the communication via transmission
element to the computer.
