VVX
The VVX can theoretically be installed anywhere in a straight pipe.
•
•
Flow sensors with plastic pipe sections must be installed in the pipeline without me-
chanical stress.
• Possibility of run empty
• Possibility of bubble-formation
Recommended length of inlet and outlet sections
Inlet section X1
Outlet section X2
•
The flow sensor can be installed in horizontal and vertical pipelines. The flow sensor is
only suitable for use in completely filled pipelines.
Vortex flow sensors are not completely independent of the flow profile due to their prin-
•
ciple. Straight lengths are essential for this.
In order to achieve the highest possible measuring accuracy, the internal diameter of
the pipe must correspond to the VVX diameter (VVX15 = 13 mm • VVX20 = 19 mm •
VVX25 = 25 mm • VVX32 = 32 mm • VVX40 = 40 mm).
