If all wirings are normal through inspection in case of a fault, after ultrasonic level
meter is grounded, you can keep pressing " ", then press "SET" to show echo me-
nu, take a photo of the echo menu and send it to us via MMS or picture. By this way,

Level meter does not
work.
Power supply is not well
connected.
Inspect power line.
Level meter does not
display data.
1.Power supply is not well
connected.
1.Inspect power line.
2.Wiring between LCD and
mainboard falls off or comes
loose.
2.Inspect the wiring and con-
nect it again.
3.The LCD is damaged.
3.Maintain it in the factory.
Level meter works but
there is no change of
trumpet icon ( ) on the
LCD, which means that
the system is in wave
loss state.
1.The measured area is be-
yond the measuring range of
level meter.
1.Replace the level meter
with a level meter with grea-
ter measuring range.
2.The measured medium
has strong disturbance, vib-
ration or heavy dust.
2.The meter will restore the
normal measurement auto-
matically after the measured
medium gets back to calm.
3.There are strong interfe-
rence sources around such
as frequency converter and
motor.
3.Check surrounding environ-
ment and realize good elect-
romagnetic shielding. Do not
share one power supply with
frequency converter and mo-
tor, and make it grounded re-
liably.
4.The probe is not aligned to
the measured surface.
4.Reinstall probe and make it
perpendicular to liquid surfa-
ce.
5.There are redundant ob-
jects in the measured space,
such as support rod and
feed opening.
5.Select an appropriate posi-
tion for installation and pre-
vent an interfering object.
6.The liquid level is in a
blind area.
6.Raise the installation posi-
tion of probe.
7.The measured medium is
soft powder or there is foam
on liquid surface.
7.Check whether the medium
is powder. If so, consult the
manufacturer.
