2.6.1.2.1 Liquid media

● In the case of vertical pipelines the monitoring head should be installed where the flow is

rising, if possible.

● For horizontal pipelines the monitoring head should be mounted on the underside of the

line (suspended).

● The monitoring head should be installed only in a straight section of piping. There should

be a distance of at least 20 pipe diameters before the monitoring head, and 5 pipe diam-

eters after the monitoring head before or after bends and changes in pipe diameter, to

avoid any effects of turbulence (fig. 3).

● Flow past the sensor should be from the side marked with a green dot.

2.6.1.2.2 Gases

If gases are to be monitored, the mounting attitude of the monitoring head is unimportant in either

vertical or horizontal pipelines. There should be a distance of at least 20 pipe diameters before the

monitoring head, and 5 pipe diameters after the monitoring head before or after bends and

changes in pipe diameter, to avoid any effects of turbulence (fig. 3).
