Problem Probable cause Solution
The screen shows
empty pipe
Pipe is empty
Make sure that the pipe is
completely full, for example,
installing the flowmeter in a vertical
pipe with upwards flow
The functional earth is not
connected
Connect the functional ground of
the flowmeter 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 flowmeter 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 flowmeter is
adequate for this application
The instrument is misaligned
Align according to point 5.2 on
page 14
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 35)
The instrument is mounted
perpendicularly to its correct
position
Install the instrument correctly (see
point 5.2 on page 14)
The instrument displays
a value when there is not
flow
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 flowmeter to a metallic point of
the installation in contact with the
liquid
The instrument is mounted
perpendicularly to its correct
position
Install the instrument correctly (see
point 5.2 on page 14)
