When encountering an error, after checking that all the wiring is normal, and after grounding the
ultrasonic level gauge, we can first install “▲” and then hold down “SET” to display the echo
menu map. Take the picture and send it to us by MMS or photos, and then you can judge the possible
phenomena such as electromagnetic interference, false echoes, entering the blind zone, not receiving
echo signals.
Phenomenon
Level gauge
does not work
Level meter
does not display
The level gauge
works, the screen
shows that the
small horn symbol
has not changed,
as shown in the
figure "▲", the
system enters the
state of losing
wave.
The reason
Power is not connected
1. The power is not connected well
2. The LCD screen is disconnected from
the motherboard or loosened.
3. LCD screen is damaged
There is foam on the surface of the
tested liquid, and the area covered by
the foam exceeds 30% in the
ultrasonic irradiation range.
1. The measured distance exceeds the
level measurement range
3. There are strong interference
sources such as inverters and motors
7. The tested medium is a soft powder.
5. There are extra objects in the
measured space, such as support
rods, feeding openings, etc.
2. The measured medium has strong
disturbance, severe vibration or dust
4.The probe is not aligned with the
plane to be measured
6. Liquid level enters dead zone
Solution
Check the power cord
1. Check the power cord
2. Check the wiring and reconnect.
3. Return to factory for repair
5. Reselect the appropriate installation
location to avoid interference
6. Raise the probe installation position.
4. Reinstall the probe perpendicular to the
liquid surface
It is necessary to filter the foam in the water
inlet part, or put the ultrasonic level gauge in
the waveguide to measure, to avoid the
influence of foam.
7. If it is a powder, consult the manufacturer.
1. Consider replacing the level gauge with a
larger distance than the existing
measurement
3. Check the surrounding environment and
do electromagnetic shielding. Do not use the
same power supply with the inverter and
motor, but also reliably ground.
2. After waiting for the measured medium to
calm down, the device will automatically
resume normal measurement
