How to Troubleshoot and Repair Common Faults of an Ultrasonic Level Gauge?
Like all equipment, ultrasonic level gauges have a limited lifespan and require proper care during operation. Over time, repeated use can lead to aging and performance degradation. This article provides detailed guidance on common faults of ultrasonic level gauges and how to maintain them effectively.
First, if the meter does not display any reading or is not working, check the power supply. Ensure that the DC24V power is correctly connected and verify the wiring for any errors. A faulty power connection is often the root cause of such issues.
Second, if the instrument displays readings but the level gauge fails to detect the correct liquid level, it could be due to misalignment with the material surface. The surface might be uneven, or there may be a thick layer of foam on top of the liquid. Additionally, if the container is empty and the bottom is not flat, the measurement range may be exceeded. To resolve this, adjust the installation angle using a level tool, or install a plastic tube in the container (as described in the installation guide). Consider using a level gauge with a larger measurement range or alternative measurement methods. If the issue persists after feeding or filling, consider upgrading to a more advanced model.
Third, if the display is unstable or the measured values show significant deviation, it may be due to the level entering the blind zone, unstable power supply, strong electromagnetic interference, or objects blocking the sound waves. Also, if the probe’s emitting surface comes into contact with metal flanges, it can affect accuracy. Solutions include using a higher safety-level gauge, ensuring the level doesn't rise too high, improving power stability, adding shielding, adjusting the installation position, or isolating the metal parts with a rubber mat.
