Caution!
Please note the following prior to mounting:
• 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 pipe 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 gaskets provided
by Endress+Hauser for the wafer version have therefore an inner diameter with a bigger inner
diameter than the piping.
• Ensure that the arrow on the measuring pipe matches the direction of flow in the piping.
• Lengths:
– Prowirl W (wafer version): 65 mm (2.56 inch)
– Prowirl F (flanged version) See Technical Information TI070D/06/en.
