5.6 ADVANCED configuration
Comment: The following description will be restricted to the additional functions of advanced configuration
as compared with the configurations defined previously (simple and normal). The common base already
explained above in this document is not repeated in this section.
5.6.1 "Pipe/fluid configuration" menu
1) Delta V filtering
When a filter has been activated, it is possible to request that the flow meter disables the filter if the
measurement changes very quickly. This provides a filter which is sufficient to comfortably see the change of
the measurement and to retain reactivity while not filtering large variations in velocity:
2) Material of the pipe wall
In Advanced mode, you can define the wall through 3 different materials/layers. On the image below, #1 is
the external material/layer, #2 and #3 follow in order towards the inside of the pipe. The materials/layers
are deactivated if NONE is selected on the material line. To activate a material/layer, choose the material
and adjust its thickness. All type of material/layers can be used as long as they can transmit ultrasounds. If
you cannot find your material in the predefined list, select
OTHER and enter in addition of the thickness
your material’s speed of sound.
