10 TROUBLESHOOTING
Problem Probable cause Solution
The associated
electronics does not
totalize
Blockage or friction of the
turbine propeller by particles
Install a filter according to
specification (maximum mesh
size = 200 µm).
Damaged pickup Change the pickup
Disconnected cables between
the turbine and the associated
electronics
Check the cable connection
The associated
electronics totalize less
than the actual volume
Blockage or friction of the
turbine propeller by particles
Install a filter according to
specification (maximum mesh =
200 µm).
The associated
electronics totalizes
more than the actual
volume
Presence of air pockets Control the minimum tank level.
Provide an air degasser
upstream of the turbine if air
intakes can be expected.
Excessive emptying of storage
tanks
The pipe is not completely full
Make sure that the pipe is
completely full, for example,
installing the flowmeter in a
vertical pipe with upwards flow
Straight pipe sections before
and after the flowmeter have not
been kept Check that there are enough
straight pipe sections as
indicated in point 3.4.
The flow rate indicated by
the associated equipment
is unstable
