- Depth measurement
Common problems and solutions guidance during installation
| Fault description | cause of issue | Solution |
| Meter does not display, does not work | Wrong power supply Wrong wiring | Check whether the DC24v power supply is correct Check whether the wiring is correct |
| The instrument has display, does not work | 1. The level gauge is not aligned with the liquid level or material
level 2. The liquid level fluctuates greatly 3. The material surface is extremely uneven 4. The liquid surface has a thicker foam layer 5. The bottom of the container is not flat after the liquid is emptied and the material is emptied 6. Out of measurement range | 1. Adjust the alignment direction of the level gauge, and use a
spirit level to calibrate and add a plastic tube to the container 2. Use a level gauge with a larger range 3. Use a level gauge with a larger range or other measurement methods 4. Naturally resume work after adding liquid or material 5. Use a level gauge with a larger range |
| The instrument display is unstable or the measured value has a large deviation | 1. The material level enters the blind spot 2. The distance measurement value is greater than the installation height 3. There is strong electromagnetic interference 4. Objects that block sound waves 5. A metal flange is prepared on the level meter 6. The emitting surface or side of the probe is in contact with metal | 1. Elevate the level meter or prevent the level from being too high 2. Modify the installation height to the correct value 3. The instrument must be connected to the ground, and shield the level gauge 4. Change the installation position or add plastic pipes 5. Switch to plastic flanges 6. Use rubber pads to isolate from metal |
For the container with the installation port or the probe placed in
the round pipe, the length of the flange connection of the 4m, 6m
and 8m type level gauge container should be less than 400mm, and
the length of the 12m level gauge container should be less than
400mm.
150mm, 15m, 20m, 30m level sensor probes should protrude from the
installation port.
