VVX
The VVX can theoretically be installed at any location on a straight pipe.
•
•
Flow sensors with plastic pipe sections must be installed in the pipeline stress-free.
• Possibility of run empty
• Possibility of bubble-formation
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. A calming section is therefore necessary.
In order to achieve the highest possible measuring accuracy, straight inlet and outlet
pipes with an appropriate inner diameter should be used (VVX15 = 13 mm •
VVX20 = 19 mm • VVX25 = 25 mm • VVX32 = 32 mm • VVX40 = 40 mm).
Technical changes reserved
