"
Caution!
• Prior to installing the measuring device in the piping, remove all traces of transport packaging
and any protective covers from the sensor.
• Make sure that the internal diameters of seals are the same as, or greater than, those of the
measuring tube and piping. Seals projecting into the flow current have a negative effect on the
vortex formation after the bluff body and cause inaccurate measurement.
• The direction of the arrow on the measuring tube must match the direction of flow.
• Lengths:
– Prowirl W (wafer version): 65 mm (2.56 in)
– Prowirl F (flanged version)  associated Technical Information on CD-ROM
