How to Troubleshoot and Repair Common Faults of Ultrasonic Level Gauges?
Like all equipment, ultrasonic level gauges have a limited lifespan and require proper care during use. After long-term operation, they may experience wear and tear, leading to performance issues. This article provides detailed guidance on common faults and maintenance methods for ultrasonic level gauges.
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 one of the most common reasons for failure.
Second, if the instrument displays data but the level gauge is not aligned with the actual liquid level, it could be due to an uneven surface, excessive foam, or a fluctuating material surface. In such cases, adjust the installation position of the sensor. You can use a horizontal level tool and install a plastic tube in the container (refer to the installation guide). If the issue persists, consider using a level gauge with a larger measurement range or alternative measurement methods. Also, ensure that the container’s bottom is flat when empty, as an uneven base can affect readings.
Third, if the display is unstable or the measured values show significant deviations, it may be due to the level entering the blind zone, unstable power supply, electromagnetic interference, or objects blocking the sound waves. Additionally, if the probe is in contact with metal surfaces or flanges, this can cause inaccurate readings. To resolve these issues, you can install a higher-level gauge, improve the power supply stability, add shielding, or reposition the sensor. Using a rubber mat to isolate the probe from metal surfaces can also help.
