11 TROUBLESHOOTING
Problem Probable cause Remedy
The flow rate is not
displayed. In its place
there are dashes
The pipe is empty.
Make sure that the pipe is
completely full, installing the flow
meter in a section upstream of the
pipe.
The functional earth is not
connected.
Connect the functional ground of
the flow meter to a metallic point
of the installation in contact with
the liquid.
Isolation of the electrodes. Clean the sensor electrodes.
Electrode cable disconnected
Connect the cable between the
sensor and the electronic
converter.
Liquid with very low conductivity
The flow meter is not adequate for
the application.
The flow rate is
unstable
Dirt on the electrodes. Clean the sensor electrodes.
The product contains air or non-
conductive particles in suspension. Verify that the flow meter is
adequate for this application.
Alignment of the sensor (Flomat)
Verify that the orientation of the
sensor is such that the arrow is
orientated along the direction of
the fluid.
The flow rate displayed
is 0
Coil cable disconnected
Connect the cable between the
sensor and the electronic
converter.
The flow rate is smaller than
programmed as CUT OFF. Decrease the value of the cut off
(see page 9).
The sensor is damaged due to
electrodes corrosion. Electrode material not adequate
for the liquid.
The functional earth is not
connected and the empty pipe
option is OFF.
Connect the functional ground of
the flow meter to a metallic point
of the installation in contact with
the liquid.
The flow rate displayed
is higher than expected The electrodes are immersed but
the pipe is not completely full.
Make sure that the pipe is
completely full, installing the flow
meter in a section upstream of the
pipe.
The instrument displays
a value when there is
not flow
