3.6 Horizontal (long) pipes
Horizontal pipes are ideal to install a clamp-on, recommended orientation 45-90 degrees refer
to
Inlet, outlet and recommended mounting area
on page 31.
In cases that a full pipe condition is not guaranteed (or not possible):
• Install on a slightly ascending pipe section or at the lowest point of the pipe system.
• Install air/gas release devices (air vent).
• If not possible, control the flow velocity to prevent gasses (air, gas or vapour) from collecting
in the upper part, so these will continuously be taken with the flow.
• In partially filled pipes, the clamp-on flowmeter will report incorrect or no flow rates.
3.7 Bends in 2 or 3 dimensions
Figure 3-2: Install on a slightly ascending pipe section
Figure 3-3: 2 and/or 3 dimensional bends upstream of the flowmeter
1 2 dimensions = X/Y
2 3 dimensions = X/Y/Z
Inlet length:
for 2 path using bends in 2 dimensions: t 10 DN; when having bends in 3 dimensions: t 15 DN
for 1 path using bends in 2 dimensions: t 20 DN; when having bends in 3 dimensions: t 25 DN
2 dimensional bends occur in a vertical or
oror
or horizontal plane (X/Y) only, while 3 dimensional bends
occur in both vertical and
andand
and horizontal plane (X/Y/Z).
