12. Chose best location for DUC-WF transducer installation.
Straight run should be 10x diameter (inlet) and 3x diameter (outlet) in order to achieve best accuracy.
When using horizontal pipe, we recommend mounting the transducers at 10 o’clock or 2 o’clock
position to avoid any influence of gas bubbles / sedimentation might accumulated on top / on bottom
of pipe

bar and mounted at app. 9 o`clock

The transducers are fixed to the pipe by using metal belts. The metal belts are tightened by using
tightener (picture in the middle). The length of the belt is designed for the biggest pipe size that the
transducer can cover. So for (significantly) smaller pipes it might be reasonable to shorten the belts
in order to make tightening easier. Please feed the belt into the tightener as shown in picture on
the left. Proceed in the same way for PT100. Put between PT100 and surface of the pipe also
acoustic coupling gel in between. After installation, PT100 should be insulated to minimize the
influence of ambient air temperature.

11 Set Zero Point (if possible)
If there is the chance to create „zero flow“ please select „Zero Setup“ and set zero point.
12. Go back to main menu and select button „MEAS“ . You enter the measuring
menu where you see the calculated flow, velocity,….
Change units:
->Go to main menu and select SETUP - > COMPL SETUP. Then select „UNITS SETUP“ to change units.
13. Activate Outputs
->Go to main menu and select SETUP - > COMPL SETUP. Then select “I/O-SETUP” and set digital and/or analogue outputs.
