INstallation
→ Install the device on the pipe to have the upstream and down-
stream distances respected according to the design of the
pipes, refer to standard EN ISO 5167-1 and Fig. 8:
50 x DN 5 x DN
40 x DN 5 x DN
25 x DN 5 x DN 20 x DN 5 x DN
18 x DN 5 x DN 15 x DN 5 x DN
With control valve Pipe with 2 elbows at 90° in
3 dimensions
Pipe with 2 elbows at 90° Pipe with 1 elbow at 90° or
1 T-piece
With pipe expansion With pipe reduction

design of the pipes.
→ Respect the following additional mounting conditions to ensure
that the measuring device operates correctly:
- We recommend to install the device at a 45° angle to the hori-
zontal centre of the pipe to prevent deposits on the electrodes
and false measurements due to air bubbles (see Fig. 9);
45°
45°

- Ensure that the pipe is always filled in the section around the
device (see Fig. 10).
- When mounting vertically ensure that the flow direction is in an
upward direction (see Fig. 10).
- Prevent the formation of air bubbles in the pipe in the section
around the device (see Fig. 11).
- Always mount the device upstream a possible injection point
in the pipe of a high-conductivity fluid (for example: acid, base,
saline,...).
