4. Safety Information
Always observe the following safety precautions to prevent injury and damage to the device:
- Ensure the power supply is disconnected before installation or maintenance.
- Only qualified personnel should perform electrical connections.
- Do not expose the sensor to corrosive substances beyond its specified material compatibility.
- Verify that the installation environment is within the specified operating conditions.
- Avoid physical impact to the sensor, especially the transducer surface.
5. Setup and Installation
Proper installation is crucial for accurate and reliable operation. Follow these steps:
- Mounting Location: Select a mounting location directly above the liquid surface, ensuring the ultrasonic beam has a clear path to the liquid without obstructions. Avoid mounting near inlets, outlets, or agitators that may cause turbulence.
- Installation Height: The sensor should be mounted such that the liquid level remains outside the sensor's blind zone (0.25-0.6m from the transducer face). Refer to the installation diagram for optimal placement.
- Secure Mounting: Use the M60 installation interface to securely mount the sensor. Ensure it is stable and perpendicular to the liquid surface.
- Electrical Connections: Connect the DC 24V power supply and 4-20mA output wiring to the built-in terminals. Refer to the wiring diagram section for detailed instructions. Ensure all connections are tight and insulated.
- Power On: Once all connections are secure, apply DC 24V power to the sensor. The LED display should illuminate.

- Cable Integrity: Check all wiring and cable connections for signs of wear, corrosion, or damage. Ensure they are securely fastened.
- Environmental Check: Verify that the operating environment remains within the specified temperature and pressure ranges.
- Recalibration: If measurement accuracy drifts over time or after significant environmental changes, recalibration may be required. Refer to the parameter settings section for guidance.
10. Troubleshooting
If you encounter issues with your ultrasonic water level sensor, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
