MALFUNCTIONING
POSSIBLE CAUSE
SOLUTION
The flow reading is very unstable.
Caused by HYDRAULIC failure:
Air bubbles or unstable flow
(vortex motion). The minimum
required linear distances
upstream and downstream of the
device were not complied with.
Check for the minimum required
linear distances upstream and
downstream of the device.
Check for the presence and
correct installation of vents on
the pipe to avoid the presence of
air in the pipe.
Caused by ELECTRIC failure:
Grounding missing or performed
improperly, oxidized nodes, very
noisy ground point, usually in
common with the grounding
systems of pumps or inverters.
Change the grounding point or
preferably create a new one for
the exclusive use of the meter.
NOTE: If with full pipe and stable liquid an unstable reading can be
observed (which varies rapidly) then most likely it is a problem of
electrical noise.
Only if necessary, set the filters in the following way:
• Set the damping to 150
• Reduce the peak cut off filter
• Increase the bypass filter
