13. APPENDIX - TROUBLESHOOTING
SYMPTOMS POSSIBLE REMEDIES
The converter shows a
flow rate even
there is static or no
flow
• There is air in the pipe, try to avoid the creation of bubbles selecting a
more suitable position for the sensor (see installation paragraph).
• Check that the sensor is full with liquid.
• Electrical conductivity of the liquid is too low or is not compatible with the
material used for the sensor electrodes.
• Perform manual zero calibration if necessary (Menu - Parameters, sub-
menu - zero calibration).
Flow reading is highly
unstable.
Possible causes are:
1- HYDRAULIC
Air bubbles or unstable flow (vortex motion). The minimum required linear
distances upstream and downstream of the device were not complied
with.
2- ELECTRIC
Grounding missing or done in an incorrectly way, 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 as follows:
• Set Damping to 150
• Reduce the peak cut filter
• Increase the bypass filter
External pulse totalizer
shows results different
from the expected
ones.
Test the output with the external flow simulator and the converter-pulse
counter system, simulating a flow rate through System > Simulation.
